| Abstract: | (Cu60Zr30Ti10)98Y2 bulk metallic glass(Φ4 mm×70 mm) was obtained successfully by copper mould cooling and spraying-casting,and some samples were isothermally annealed at temperatures of 473 and 623 K,which was lower than the glass transition temperature(Tg) for 1 h.Microstructure and properties of as-cast and annealed samples were studied.Crystallization phases(Cu10Zr7 and CuZr) were observed in annealed samples,and the species and fraction of these phases increased with increasing annealing temperature.Mic... |
