Under the supervision of Professor Stefan Pogatscher and in collaboration with a strong scientific network, I am delighted to share our two “most fresh” papers pushing up the frontiers of Aluminium Metallurgy.
The first “Age-hardening response of AlMgZn alloys with Cu and Ag additions” is a comprehensive assessment on the heat-treatment response and mechanical properties of an emerging class of Aluminium alloy known as “crossover alloys”. Disruptive science guys! The paper is led by Lukas Stemper, a bright young PhD candidate and one of the bests metallurgists I have worked in my scientific life. An exciting collection of new science will also come out from this research very very soon!

In the second paper — “Warm-forming of pre-aged Al-Zn-Mg-Cu alloy sheet” — the highly-motivated and smart Dr. Johannes Österreicher (from the Austrian Institute of Technology) develops a new strategy for warm-forming the Aluminium alloy 7075 which is an important material not only in aerospace, but also in the automotive industry. In the paper, Dr. Österreicher shows a potential new hexagonal-compact phase within the 7xxx alloy system after paint-bake treatment. Such conclusion was reached after exhaustively attempts to crystallographic index the observed phase with the existing knowledge on 7xxx series alloys. Very nice work from Johannes with deep implications in modern technology of Aluminium alloys.

Both research were supported by the European Research Council excellent science grant “TRANSDESIGN” (no. 757961) and by the Austrian Research Promotion Agency (FFG) in the project 3DnanoAnalytics (FFG-No 858040). We are of course very grateful for this work opportunity!
