Such alloys would be key for circumventing today's common multi-material mixes and facilitate the recycling of complex products such as automobiles.
Tear down established boundaries
A team of researchers led by Univ. Prof. Dr. Stefan Pogatscher from the Department of Nonferrous Metallurgy at the University of Leoben has been trying to tear down these established boundaries between classes of aluminum alloys for several years. Pioneering work has been done in this regard, so that it has now been possible to further establish this new field of research in a review article in the prestigious journal "Progress in Materials Science".
"The focus of our work is on combining material properties of the conventional alloy classes 2xxx, 5xxx and 7xxx into a single superior material. Recent research data provides clear indications of good forming performance combined with high age-hardening potential - characteristics that are usually difficult to combine. In addition, other surprising properties show to be important for applications in space technology," explains Dr. Lukas Stemper, PostDoc at the Christian Doppler Laboratory for Advanced Aluminum Alloys. These new materials – termed as "crossover alloys" – are now being presented by the researchers at Montanuniversität as a new aluminum classification that is capable of combining the benefits of several commercial alloy classes.
In the first place
The journal Progress in Materials Science (IF 39.58) is ranked first in materials science in Scopus. Only authoritative reviews of recent advances in the science of materials and their exploitation in engineering and other applications are published. Authors must be identified as leaders in their respective field. The review article "On the potential of aluminum crossover alloys" is the first article in the new "snapshot review" category, which addresses very young fields.
