Congratulations!

In his guest lecture at Graz University of Technology, Dr. Mario Boccalini, Researcher at IPT – Instituto de Pesquisas Technologicas / Institute for Technological Research in Brazil, will first give a brief overview of the work portfolio at IPT. He will talk about Advanced Materials and their Technological Axes. Also, he will show examples of past and further research projects as a starting point for discussing possibilities of collaborative work with TUGraz.

A large amount of the engineering work for the aircraft structure development is related to fatigue and damage tolerance. In the lecture, first a short overview of the fundamentals of fatigue and fracture mechanics disciplines will be presented. Lessons learned from the past will help to explain the evolution of philosophies for fatigue evaluation, from safe-life to fail-safe, and then to damage tolerance. The present fatigue and damage tolerance requirements will be also discussed in short.

It can be said that the aviation and mobility industries is experiencing a revolution period in terms of new technologies. The lecture closes with an overview of future challenges on the development of aircraft structures, such as damage tolerance for composite and hybrid structures, new materials, additive manufacturing, smart structures, and others.

The above topics will be addressed by Dr. Carlos Chaves, Principal Structures Engineer at Embraer, in his guest lecture at Graz University of Technology.

One characteristic of the gas and steam turbines built since 1929 by BBC / ABB / Alstom and today GE is that the rotor is welded from individually tempered forged components. With more than 89 years of experience with welded rotors for steam turbines, gas turbines and turbogenerators, GE has successfully welded together more than 7800 turbine rotors. Rotor welding technology can also be used to repair damaged rotors of any type if welding is possible.

In his guest lecture at Graz University of Technology, Sorin Keller, Manager Welding & Brazing Technology – GE Power Switzerland and President of the International Institute of Welding, talks about past developments and future challenges.

A major challenge in future will be to reliably weld established and new materials. The focus is on rationalising welding processes to increase the efficiency of power plants and thus make a lasting contribution to protecting the environment.

As the Welding Engineering undergraduate programme at The Ohio State University (OSU) is completing 75 years in 2023, it has evolved to become a key player in the education and research on materials joining within the U.S. and across the world. In 2010 OSU joined efforts with the U.S. National Science Foundation (NSF) and other key universities across North America to establish the Manufacturing and Materials Joining Innovation Center (Ma2JIC). This center has brought together researchers from seven different universities in U.S. and Canada and more than 60 industrial and government organisations from around the globe to cooperatively develop state-of-the-art and economically relevant research on materials joining and metal additive manufacturing (AM), totaling more than US$50M. Today Ma2JIC invests $5.5M per year to support approximately 30 different research projects, which involve about120 researchers and students across The Ohio State University, University of Tennessee-Knoxville, Pennsylvania State University, Colorado School of Mines, and the University of Waterloo.

In his Guest Lecture, Antonio J. Ramirez from Ma2JIC will present highlights of the research and technologies developed by OSU and Ma2JIC, ranging from fundamental studies on solidification cracking during welding and Additive Manufacturing, powder- and wire-based metal AM, and conventional welding processes like friction stir welding and resistance spot welding of advanced steels and dissimilar materials.

GE has many years of experience with welded rotors for steam, gas turbines and turbogenerator rotors. From 1929 to the present, more than 7,800 rotors have been manufactured from identical materials or different combinations of materials. The future challenge lies in mastering the welding technology on new materials, as well as in further optimizing and streamlining the welding processes, with the aim of increasing the efficiency of the power plants. The greatest challenge lies in the development and implementation of repair processes that ensure the operation of these machines to a modern environmentally friendly standard, thus making a sustainable contribution to the conservation of resources and the environment. In the context of these developments, failure analysis is an essential tool that is used to bring reliable products to market.

A constant motivation in aeronautical engineering is the research of new materials that enable the weight reduction of flying objects without reducing their strength and thus effectively decrease their fuel consumption. However, since most of today’s commercial airplanes and helicopters are powered by fossil fuels, a reduction of the CO₂ emissions towards zero is not possible. Therefore, another research focus is looking at the development of alternative propulsion systems that can reduce CO₂ emissions even further and thus effectively counteract future climate changes.

In the course of the FFG-funded project IonAs, an all-electric propulsion system powered by ion wind was studied by IMAT in cooperation with the IHS (Institute of High Voltage Engineering and System Performance – TU Graz) and the IAV (Institute of Aviation – FH-Joanneum). Due to the fact that such ionic wind powered systems provide much lower thrust than conventional systems, weight reduction is even more important. This goal can be achieved by combining lightweight materials and additive manufacturing (in this case Laser – Powder Bed Fusion), which enables the production of highly complex parts that cannot be manufactured in any other way.

In this project, the team has successfully manufactured a hybrid demonstrator in the shape of an air foil that consists of two parts: The front part was additively manufactured with the use of AlSi10Mg alloy and shows the possibility of printing small structures of 200µm in thickness. The rear part of the air foil was made out of CFRP (Carbon Fibre-Reinforced Polymer) and was manufactured by the colleagues of IAV. Due to the great outcomings of this project, the follow up FFG-project IonAs² was approved and is already running, including two additional project partners (Institute of Fluid Mechanics and Heat Transfer – TU Graz and Institute of Electrical Measurement and Sensor Systems – TU Graz), with the aim to bring the idea of flying with the power of ions to a new level!

On the occasion of the event "From Science to Innovation" on 9th of November at the Karl-Franzens University the Technische Universität Graz honors its inventors.
The award "Inventor of the TU Graz" was given to Sergio T. Amancio Filho, Christof Sommitsch, Pedro Effertz and Mohammad Reza Ahmadi (from left to right) for their groundbreaking inventions in the field of materials science.

The development of structural shape-memory alloys dates back the 1940s and 1950s, being the most employed alloy the well-known Nitinol (or NiTi). Due to the shape memory effect, these functional metals have the ability to be deformed and recover their shape when heated. In a nutshell, these functional effects deliver high stresses, therefore enabling Nitinol to be used as an actuator. However, their use in main stream functional-structural applications has been somehow hindered mainly to their complex processing, machining, and high reactivity. Additive manufacturing has the potential to mitigate these drawbacks, as near-net shape parts can be produced with lesser manufacturing steps and higher materials savings. In our recent publication https://doi.org/10.1177%2F1464420720975059 we have shown that NiTi alloys can be successfully additively manufactured with electron beam free forming fabrication (EBF3), also known as wire-based electron beam additive manufacturing (w-EBAM). The project has been led by Rafael Paiotti, project assistant and PhD candidate at BMK Endowed Professorship of Aviation in close collaboration with Florian Pixner from the Joining Technology group  Printed parts were tested in cooperation with Institute for Chemistry and Technology of Materials, under ad-hoc consultancy of Embraer.

Vienna, 9/26/2020

The 1^st Meeting of the Brazilian Scientific Diaspora was held on 9/26/20, in Vienna, with the presence of the Minister of Science, Technology and Innovations, Mr. Marcos Pontes, the Ambassador of Brazil in Vienna, José Antônio Marcondes de Carvalho, and 21 researchers, residing in Austria and Slovakia. The meeting was opened with the words of the Ambassador of Brazil to Austria, which was followed by a speech by Minister Marcos Pontes and interactive debate with members of the diaspora. In his opening speech, Ambassador Marcondes highlighted the importance of observing the phenomenon of emigration of qualified professionals from the perspective of networks formed by researchers, instead of a concept exclusively of “brain drain”. He noted the diversity of present researchers, coming from different regions of Austria, and with different areas of expertise. The Brazilian Ambassador stressed the fact that ‘Brazil is an innovative and creative country’ and mentioned ‘the mobilization of Brazilian scientific diasporas abroad as one of the main tools to increase the scientific and technological cooperation between Austria and Brazil.’

Minister Marcos Pontes – an engineer and retired NASA astronaut - welcomed the organization of the meeting of the Brazilian scientific community in Austria, highlighting the importance of technology in human development and the fundamental role played by science, technology and innovation. Following topics were discussed in this meeting: (a) exchange of Brazilian and Austrian students, by supporting partnerships between research and teaching institutions in both countries; (b) identification of new R&D trends in Austria as a way to contribute to the establishment of new topics in Brazil; (c) Creation of an association for the Brazilian diaspora in Austria to foster the above-mentioned topics.

Marina Melo Gontijo, Willian Sales de Carvalho and Prof. Sergio Amancio (in the picture with Minister Marcos Pontes) had the honor of representing TU Graz and IMAT in this important event.

In his opening speech, he introduced the impressive development of Graz University of Technology and responded to the contribution on this success of Em.Prof. Horst Cerjak, the person celebrating his big birthday. The head of the institute, Prof. Christof Sommitsch, subsequently paid tribute to his predecessor Em.Prof. Dr.mont. Horst Cerjak on his 80^th birthday by pointing out selected contributions from his very fulfilling and and successful professional life. Afterwards Prof. Sommitsch presented an overview of the ongoing and prospective main topics of the institute.

In the first block of the event, two specialist lectures on current research topics were presented. Mr. F. Pixner talked about the wire based additive manufacturing as part of joining technology and Dr. M. Skalon presented the powder bed process, where he focused his lecture on an innovative approach to parameter development of new powders. After the coffee break Prof. G. Wilhelm, who also works for Lorch Schweißtechnik GmbH, introduced his research results of the MSG build-up welding processes of iron-tungsten pseudo-alloys under consideration of the welding process. Mr. E. Wagner focused then on the current situation of the additive manufacturing with electron beam in general and in particular on features at pro-beam GmbH. Ms. A. Putz presented parts of her PhD thesis in the field of flux-cored wire welding of standard duplex steel, notably the very innovative AHT method. After lunch, Mr. Th. Willidal (voestalpine Böhler welding Austria) presented the concept of the flux cored wire in general and in particular the implementation for a nickel-based alloy. Mr. H. Staufer from Fronius International GmbH, demonstrated the possibilities and potential of the laser-MAG tandem hyprid process in terms of the large tolerance to variable gap dimensions. Next, Prof. Amancio presented selected methods for joining dissimilar compounds, paying particular attention to the friction-based processes. The last presentation of Ass.Prof. Domitner focused on the simulation of self-pierce riveting in modern car body construction.

At the end of the seminar guided tours through the labs of the institute were offered. Summing up the Materials Day showed current trends and innovative solutions in modern joining technology from a scientific and industrial point of view and everybody had the chance of interdisciplinary discussions and networking.

Recently the STYRIAM METALS team took part in Fifteen Seconds Festival from 6 - 7 June 2019 in Graz and gave a pitch about the product.

STYRIAM METALS is a start-up team located in Graz (Styria, Austria) at TU Graz working on metallic powders for Additive Manufacturing.

Head of the team is Mr. Mateusz Skalon from IMAT.

The team develops a modification process of steel powders utilised for Selective Laser Melting (SLM). The powder modification allows to eliminate the need of supporting the printed components during the printing process. This extends a freedom of design by enabling a unique feature of horizontal printing without supports. With this unique technology it is planned to enter the rapidly growing market of additive manufacturing.

STYRIAM METALS is an outcome of FFG Spin-Off Fellowship programme: NewGen SLM Powder.
