Freezing solute atoms in nanograined aluminum alloys via high-density vacancies
Wu, Shenghua; Søreide, Hanne-Sofie; Li, Chunan; Liu, gang; Li, Yanjun; Roven, Hans Jørgen; Sun, Jun (Peer reviewed; Journal article, 2022)Low-temperature decomposition of supersaturated solid solution into unfavorable intergranular precipitates is a long-standing bottleneck limiting the practical applications of nanograined aluminum alloys that are prepared ... -
Hierarchical structure in Al-Cu alloys to promote strength/ductility synergy
Wu, Shenghua; Li, Yanjun; Roven, Hans Jørgen; Liu, gang; Sun, Jun (Peer reviewed; Journal article, 2021)Experimental evidence demonstrated that equal channel angular pressing (ECAP) at cryogenic temperature, in comparison with ECAP at room temperature, led to promoted strength-ductility synergy in an Al-2.5wt.%Cu alloy. The ... -
The interaction between vacancies and twin walls, junctions, and kinks, and their mechanical properties in ferroelastic materials
He, Xiaomei; Li, Suzhi; Ding, Xiangdong; Sun, Jun; Selbach, Sverre Magnus; Salje, Ekhard K. H. (Journal article; Peer reviewed, 2019)Vacancies strongly interact with twin boundaries and often change dramatically the properties of the ferroelastic material. However, the understanding of this behavior at an atomic-level is still deficient. Here we study ...
