Journal ArticleDOI
Bimodal microstructure - A feasible strategy for high-strength and ductile metallic materials
TL;DR: A brief overview of the available approaches based on thermo-mechanical processing technology in producing bimodal microstructure for various metallic materials is given, along with a summary of unusual mechanical properties achievable by BIMODality.
Journal ArticleDOI
Tensile properties, texture evolutions and deformation anisotropy of as-extruded Mg-6Zn-1Zr magnesium alloy at room and elevated temperatures
Huiyuan Wang,Jian Rong,Zhi-Yuan Yu,Min Zha,Cheng Wang,Zhi-Zheng Yang,Ru-Yu Bu,Qi-Chuan Jiang +7 more
TL;DR: In this article, the influence of temperature on tensile properties anisotropy and the associated change in deformation mechanisms in the range of 25-275°C of the fine-grained ZK60 alloy were investigated.
Journal ArticleDOI
Exploring the Hall-Petch relation and strengthening mechanism of bimodal-grained Mg–Al–Zn alloys
Zhong-Zheng Jin,Min Zha,Zhi-Yuan Yu,Pin-Kui Ma,Yong-Kang Li,Jin-Ming Liu,Hai-Long Jia,Huiyuan Wang +7 more
TL;DR: In this article, the Hall-Petch relation for bimodal-grained Mg-Al-Zn alloys consisting of both ultra-fine grains (UFGs) and coarse grains (CGs) is discussed separately for yield stress and flow stress according to different deformation behaviors of UFGs/FGs and CGs.
Journal ArticleDOI
Achieving dispersed fine soft Bi particles and grain refinement in a hypermonotectic Al-Bi alloy by severe plastic deformation and annealing
Min Zha,Zhi-Yuan Yu,Feng Qian,Huiyuan Wang,Yanjun Li,Ragnvald H. Mathiesen,Hans Jørgen Roven +6 more
TL;DR: In this article, 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 alloy by a complete redistribution of immISCible Bi particles and grain refinement of alloy matrix.

Controlled rolling preparation method for multicomponent and multi-scale-structure magnesium alloy with high aluminum content
TL;DR: In this paper, a controlled rolling preparation method for multicomponent and multi-scale-structure magnesium alloy with a high aluminum content is presented. But the preparation method comprises the four steps of smelting extrusion, homogenization treatment, controlled rolling and controlled recrystallization.
