Abstract

We have successfully fabricated porous Zr55Cu 30Al10Ni5 bulk metallic glassy alloy samples using a spark plasma sintering process. No crystallization was observed in the sintered porous alloy. The porosity was controlled by the sintering temperature and loading pressure. The sintered porous alloy exhibited a larger plastic ductility and lower Young's modulus than the as-cast specimen. These unique characteristics of the porous bulk glassy alloy indicate the possibility of its future applications as a new structural and functional material.
