Prominent role of multi-scale microstructural heterogeneities on superplastic deformation of a high solid solution Al–7Mg alloy
Zha, Min; Zhang, Hongmin; Jia, Hailong; Gao, Yipeng; Jin, Shenbao; Sha, Gang; Bjørge, Ruben; Mathiesen, Ragnvald; Roven, Hans Jørgen; Wang, Hui-Yuan; Li, Yanjun (Peer reviewed; Journal article, 2021)Achieving high superplasticity in single-phase Al alloys remains a challenge, since the fine-grained structure required for superplastic deformation coarsens rapidly in the absence of dispersed second-phase particles during ... -
Soft particles assisted grain refinement and strengthening of an Al-Bi-Zn alloy subjected to ECAP
Jia, Hailong; Bjørge, Ruben; Marthinsen, Knut; Mathiesen, Ragnvald; Li, Yanjun (Journal article; Peer reviewed, 2017)With the aim to improve the strength of potential Pb-free Al-Bi based bearing alloys, an Al-6Bi-8Zn alloy was subjected to equal channel angular pressing (ECAP). To reveal the roles played by the soft Bi particles, an ...
