The activity of non-basal slip systems and dynamic recovery at room temperature in fine-grained AZ31B magnesium alloys
Junichi Koike,Takayuki Kobayashi,Toshiji Mukai,H. Watanabe,Mayumi Suzuki,Kouichi Maruyama,Kenji Higashi +6 more
TL;DR: In this paper, fine-grained alloys of Mg-3Al-1Zn-0.2Mn in wt.% were obtained by an equal-channel angular extrusion technique and subsequent annealing at elevated temperatures.
Journal ArticleDOI
Deformation mechanism in a coarse-grained Mg–Al–Zn alloy at elevated temperatures
TL;DR: In this paper, the deformation behavior of a coarse-grained AZ31 magnesium alloy was investigated at elevated temperatures using commercial rolled sheet and it was suggested from the data analysis that the high ductility was attributed to a deformation mechanism of glide-controlled dislocation creep.
Journal ArticleDOI
Effect of temperature and grain size on the dominant diffusion process for superplastic flow in an AZ61 magnesium alloy
TL;DR: In this article, the effect of temperature and grain size on superplastic flow was investigated using a relatively coarse-grained (∼20μm) Mg-Al-Zn alloy for the inclusive understanding of the dominant diffusion process.
Journal ArticleDOI
Superplastic deformation mechanism in powder metallurgy magnesium alloys and composites
TL;DR: In this article, the parametric dependencies for superplastic flow in powder metallurgy (PM) magnesium alloys and composites were characterized so as to elucidate the deformation mechanism.
Journal ArticleDOI
Application of superplasticity in commercial magnesium alloy for fabrication of structural components
TL;DR: In this article, the authors investigated the superplastic properties of magnesium alloys with several grain sizes and found that grain boundary sliding took place more easily with grain refinement, and the required grain size for high strain rate super-plastic forming was estimated to be ∼2 μm.
