In order to realize biomedical applications of bulk glassy alloys, Pd-based glassy alloys with Ni-free composition were developed. The alloy with the highest glass-forming ability was obtained at a composition of Pd30 Pt17.5 Cu32.5 P20 The critical cooling rate for glass formation was measured to be 0.050-0.067 Ks. It is also recognized that the crystallization of the undercooled alloy is mainly dominated by surface nucleation. The apparent crystal growth rate of the alloy was slightly higher than that of the previously reported Pd40 Cu30 Ni10 P20 alloy at the same degree of undercooling. The highly processable feature of the alloy has potential for biomedical applications.
