Abstract

Thermal properties of a number of new Ca-based bulk metallic glasses are reported and discussed here. The compositional range of the new metallic glasses follows the formula:

CaA(Y,Ln)B(Mg,Sn)C(Ga,Zn,Al,Ag)D(Cu,Ni)E,

where A ranges from 0.40 to 0.70, B = 0 to 0.25, C = 0 to 0.25, D = 0 to 0.35, E = 0 to 0.35, A+B+C+D+E=1, and Ln represents the La group elements. The alloys have been developed based on specific criteria predicted from Senkov-Miracle topological and thermodynamic models for metallic glass formation, which narrow the compositional range for searching new metallic glasses.
