Synthesis and compressive properties of Al–Ni–Y metallic glass

An Al-based metallic glass rod with 0.75 mm diameter was prepared successfully using the copper-mould casting technique together with the proper melt treatment of the liquid alloy. The compressive properties of this Al–Ni–Y metallic glass were experimentally examined. The results showed that the amorphous alloy has a high yield strength of 1090 MPa and a compressive fracture strength of 1150 MPa. Its fracture surface presented typical vein patterns and melting phenomena characteristic of a monolithic metallic glass.

A study of CuZr-based bulk metallic glass composite dispersed by in-situ Ta particles

The microstructure and mechanical behavior of Cu46Zr41Al7Nb1Ta5 BMGC containing Ta-rich particles and B2 phase were investigated. The parabolic strain-hardening behavior is observed due to the martensitic transformation of the B2 phase. The stress behavior of B2 phase dominates the macro-mechanical behavior rather than the shear-banding deformation.
