Effect of Al Addition on Glass Forming Stability of Ca-Mg-Zn-Cu Based Bulk Metallic Glasses (PREPRINT)
Abstract
The effect of Al addition on glass forming ability and glass stability of Ca-Mg-Zn, Ca-Mg-Cu, and Ca-Mg-Zn-Cu alloys was studied. The glassy alloys were produced by a copper mold casting method as wedge-shaped samples with thicknesses varying from 0.5 mm to 10 mm. Thermal properties, such as the glass transition, crystallization and melting temperatures, as well as heats of crystallization and melting, were determined for the produced glasses. Partial substitution of Zn and/or Cu with Al was found to generally reduce the glass forming ability; however, it improves the glass stability.
