Formation and Mechanical Properties of Mg-Cu-Al-Gd Bulk Metallic Glass Composites

Abstract:

The effect of Al addition to Mg65Cu25Gd10 glassy alloy on the microstructure, thermal properties and mechanical properties were investigated. The Mg65Cu25-xAlxGd10 (x=1-7at. %) bulk metallic glass composites were formed by copper mold casting, and the fraction and size of the crystalline phases in the glassy matrix changed with the Al content. The Mg65Cu24Al1Gd10 glass composite consisted of a small amount of crystalline phases in the glassy matrix possesses high compressive strength up to about 850 MPa.
