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?

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?
