Magnesium Alloy Development for Automotive Applications
TLDR
In this article, the development of new cast and wrought magnesium alloys using computational thermodynamics tools and experimental approach is summarized, and the Mg-Al-Ca alloys show excellent creep resistance due to the formation of high-temperature (Mg,Al)2Ca phase.Abstract:
This paper summarizes the development of new cast and wrought magnesium alloys using computational thermodynamics tools and experimental approach. The Mg-Al-Ca alloys show excellent creep resistance due to the formation of high-temperature (Mg,Al)2Ca phase. The Mg-Al-Sn alloys are designed for mechanical properties and corrosion resistance through the optimization of Mg17Al12 and Mg2Sn phases in the microstructure. In the Mg-Zn-Ce system, Zn provides strength through solid solution strengthening while Ce increases the ductility via improved texture. Mg-Nd-Zn is a heat-treatable alloy system based on the precipitation hardening of Mg12Nd phase.read more

Application of texture simulation to understanding mechanical behavior of Mg and solid solution alloys containing Li or Y
TL;DR: In this paper, the viscoplastic self-consistent model was used to interpret differences in the mechanical behavior of hexagonal close packed magnesium alloys, showing that the plane strain compression textures of the alloys showed an increasing tendency for the basal poles to rotate away from the normal direction towards the rolling direction.
