Abstract

With the aim of developing a new bulk glassy alloy which can be applied to biomedical applications, we examined glass-forming ability and mechanical properties of Ni-free glassy alloys in Pd50-xPtxCu 30P20 system. As a result, the best glass-forming composition is located at Pd35Pt15Cu30P 20, and the alloy can be formed into bulk glassy rods with diameters of up to at least 30 mm by fluxed water quenching. For the bulk glassy alloy, fracture strength, fracture elongation and Young's modulus were measured to be 1590 MPa, 1.8% and 99.8 GPa, respectively, under a compressive stress and 1410 MPa, 1.7% and 83.0 GPa, respectively, under a tensile stress. These features of high glass-forming ability and good mechanical properties are expected to be used as biomedical materials.
