High thermal stability bulk metallic glass in the Zr—Nb—Cu—Ni—Al system

摘要

Disclosed is an improved bulk metallic glass alloy and methods of making the alloy in which the alloy has the structure Zr_aNb_bCu_cNi_dAl_e, wherein a-e represent the atomic percentage of each respective element, and wherein b/a is less than about 0.040, and c/d is less than 1.15. The bulk metallic glass alloy has improved thermal stability and an increased super cooled liquid region rendering it capable of being thermoplastically formed into a variety of shapes and sizes.
