Cryogenic temperature and strain rate dependence of mechanical properties for extruded AA6060 alloys
Xu, Zebing; Roven, Hans Jørgen; Furu, Trond; Jia, Zhihong ( Trans Tech Publications Ltd , 2014 , Article)Tensile properties and fracture behavior of an AA6060 alloy were investigated at room temperature (295K) and cryogenic temperature (77K). It was found that both ultimate tensile strength and elongation increased with ... -
Deep drawability and drawing behaviour of AZ31 alloy sheets with different initial texture
Zhang, Hua; Huang, Guangsheng; Fan, Jianfeng; Roven, Hans Jørgen; Xu, Bingshe Xu; Dong, Hongbiao... more authors ... less authors ( Elsevier Ltd , 2014 , Article)Repeated unidirectional bending (RUB) process was carried out to improve the texture of AZ31 alloy sheets. Compared to the as-received sheet with a strong basal texture, the RUB processed sheet with a weaker basal texture ... -
Improved mechanical properties of AZ31 magnesium alloy plates by pre-rolling followed by warm compression
Zhang, Hua; Yan, Yan; Fan, Jianfeng; Cheng, Weili; Roven, Hans Jørgen; Xu, Bingshe; Dong, Hongbiao... more authors ... less authors ( Elsevier Ltd , 2014 , Article)AZ31 magnesium alloy plates were processed by pre-rolling followed by warm compression. The corresponding microstructure evolution and mechanical properties were investigated in the present paper. The pre-introduced twins ... -
Microstructure evolution and mechanical properties of twinned AZ31 alloy plates at lower elevated temperature
Zhang, Hua; Liu, Yang; Fan, Jianfeng; Roven, Hans Jørgen; Cheng, Weili; Xu, Bingshe; Dong, Hongbiao... more authors ... less authors ( Elsevier Ltd , 2014 , Article)The AZ31 alloy plates were pre-rolled at room temperature along the transverse direction to introduce extension twinning. The effect of pre-existing twins on the mechanical properties of AZ31 alloy plates at lower elevated ...
