Abstract

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.
