摘要：

We investigated the microstructure and mechanical properties of the porous ZI(55)Cu(30)Al(10)Ni(5) bulk metallic glassy specimens fabricated by a spark plasma sintering process starting from the low sintering temperature. short holding time and rapid cooling. No crystallization within powder particles as well as at the interfaces between powder particles was identified by scanning and transmission electron microscopic observations. The sintered porous bulk metallic glassy specimens exhibited larger plastic strain and lower Young's modulus than those of the as-cast alloy specimen. The increase in the plastic strain can be related to the pores in the sintered porous bulk glassy samples which generate multiple shear deformation events.
