Microstructure Evolution and Mechanical Properties of Mg-Y-Zn Sheets

Abstract

The use of light-weight wrought magnesium for structural components is an important part of the mass reduction strategy for automobiles to improve their fuel efficiency. a potential wrought material in this context is yttrium containing magnesium alloy. in this work, two magnesium-yttrium alloy compositions were cast and rolled to 1.8 mm thick sheets. the mechanical properties of these hot rolled and annealed sheets were determined. Microstructure evolution during thermo-mechanical processing in these alloys was investigated using optical and scanning electron microscopy, as well as TEM. Precipitates evolution during the casting homogenization, rolling and annealing processes were analyzed and compared with those calculated using thermodynamic modeling (FactSage).
