摘要: The effect of Al addition on glass forming ability (GFA) and stability the glassy phase against crystallization was studied for Ca-Mg-Zn, Ca-Mg-Cu, Ca-Mg-Zn-Cu alloys. alloys were produced by copper mold casting as wedge-shaped samples with thicknesses varying from 0.5 to 10 mm. Thermal properties, such transition, melting temperatures, well heats melting, determined glasses. Partial substitution Zn or Cu found improve (GS) general tendency reduce GFA.
