Abstract

Mg-Gd-Y alloys are expected that improves mechanical properties at the room temperature. In this study, Mg-Gd-Y alloys have been investigated to clarify the effect of the Gd/Y ratio and total amount of solute atoms on age-hardening and precipitation using HRTEM and calculations of images and electron density by first principal. In the specimen at as-quenched condition, the row contrasts consisted of bright and dark dots lying on the {1100}Mg planes, which were considered to monolayer were observed.
