Achieving dispersed fine soft Bi particles and grain refinement in a hypermonotectic Al-Bi alloy by severe plastic deformation and annealing
Zha, Min; Yu, Zhiyuan; Qian, Feng; Wang, Huiyuan; Li, Yanjun; Mathiesen, Ragnvald; Roven, Hans Jørgen (Journal article; Peer reviewed, 2018)The present work revealed that equal-channel angular pressing (ECAP) deformation combined with appropriate annealing could represent as an efficient route to modify immiscible as-cast microstructure of a monotectic Al–8Bi ... -
Development and characterizationof high solid solution Al-Mg alloysand an immiscible Al-Bi alloyprocessed by ECAP and annealing
Zha, Min (Doktoravhandlinger ved NTNU, 1503-8181; 2014:149, Doctoral thesis, 2014)The thesis is based on five papers, covering two topics: papers 1-4 mainly focus on the development and characterization of high solid solution Al-Mg alloys by room temperature ECAP and annealing, their microstructure ... -
High strength and ductile high solid solution Al-Mg alloy processed by a novel hard-plate rolling route
Zha, Min; Meng, Xiaotao; Zhang, Hongmin; zhang, Xuanhe; Jia, Hailong; Li, Yanjun; Zhang, Junyu; Wang, Huiyuan; Jiang, Qichuan (Journal article, 2017)Achieving bimodal grain structure via cold rolling remains a challenge for Al–Mg alloys. In the present work, a high tensile strength (∼525 MPa) and ductile (∼14%) Al–9Mg alloy was fabricated by a novel hard-plate rolling ... -
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 ... -
Stabilizing a severely deformed Al–7Mg alloy with a multimodal grain structure via Mg solute segregation
Zha, Min; Wang, Huiyuan; Li, Yanjun; Roven, Hans Jørgen (Peer reviewed; Journal article, 2021)Single-phase Al–Mg alloys processed by severe plastic deformation (SPD) usually suffer from unsatisfactory thermal stability at moderate to high temperatures with recrystallization occurring and obvious grain coarsening. ...
