Description

Here we report on the formation of a crystalline Au-based solid solution surface layer on solidification, which is responsible for yellow color of the Au-based bulk metallic glass (BMG) samples. The structure of the BMG alloy was studied by X-ray diffractometry, scanning electron microscopy, and transmission electron microscopy. The deformation behavior of these Au-based BMG samples on heating was studied at temperatures above Tg at different strain rates.
