Dr. Aster’s Breakthrough in Aluminium Alloy Design with Cluster-Hardnening

~ Matheus A. Tunes ~ Leave a comment

In his recent work, Dr. Philip Aster delivers a remarkable contribution to the understanding of microstructural evolution in Al-Mg-Zn-Cu crossover alloys, with a particular focus on the role of copper in long-term aging (LTA) conditions. Through advanced atom probe tomography (APT), Dr. Aster demonstrates how Cu additions not only promote finer clustering and T-phase precursors … Continue reading Dr. Aster’s Breakthrough in Aluminium Alloy Design with Cluster-Hardnening

A great scientific debate: Are clusters or Guinier-Preston zones responsible for strengthening an Al-Cu-Mg alloy?

~ Matheus A. Tunes ~ Leave a comment

Feature image credits: https://www.scienceisweird.com/arguing-comics Science thrives on debate, and the historic clash between Ringer et al. and Zahra et al. over the role of solute clustering in Al-Cu-Mg alloys is a perfect example of how scientific disputes drive progress. In this case, one side argued that Cu-Mg clusters were a distinct strengthening mechanism, while the … Continue reading A great scientific debate: Are clusters or Guinier-Preston zones responsible for strengthening an Al-Cu-Mg alloy?

A giant leap on the fundamental phenomenon of age-hardening in aluminium alloys!

SIZE DEPENDENT AGE-HARDENING DISCOVERED!  The Montanuniversitaet Leoben has a small breakthrough to report. The age-hardening of metals was discovered at the beginning of the twentieth century. 110 years later, Phillip Dumitraschkewitz was able to show in his doctoral thesis under supervision of Professor Pogatscher from the Chair of Nonferrous Metallurgy, that the effect depends on the material … Continue reading A giant leap on the fundamental phenomenon of age-hardening in aluminium alloys!
