Microstructure and mechanical properties of Al-xMg alloys processed by room temperature ECAP
Chen, Yongjun; Chai, YC; Roven, Hans Jørgen; Subbarayan, Sapthagireesh; Yu, Yingda; Hjelen, Jarle (Journal article; Peer reviewed, 2012)Microstructure development and mechanical properties of Al–xMg alloys (x = 0, 1, 5–10 wt%), processed by ECAP at room temperature, have been investigated. The results show that the microstructures of Al–xMg alloys are ... -
Optimization of EBSD parameters for ultra-fast characterization
Chen, Yongjun; Hjelen, Jarle; Subbarayan, Sapthagireesh; Roven, Hans Jørgen (Journal article; Peer reviewed, 2012)Ultra-fast pattern acquisition of electron backscatter diffraction and offline indexing could become a dominant technique over online electron backscatter diffraction to investigate the microstructures of a wide range of ... -
Quantitative study of grain refinement in Al-Mg alloy processed by equal channel angular pressing at cryogenic temperature
Chen, Yongjun; Roven, Hans Jørgen; Subbarayan, Sapthagireesh; Skaret, Pål Christian; Hjelen, Jarle (Journal article; Peer reviewed, 2011)Strain induced grain refinement of an Al–1 wt.% Mg alloy processed by equal channel angular pressing (ECAP) at cryogenic temperature is investigated quantitatively. The results show that both mean grain and subgrain sizes ...
