采用熔渗法制备了毫米级W球增强Zr基大块非晶复合材料。研究了复合材料在1 × 10 - 4s-1和1 × 10 - 2s-1两种应变速率下的压缩变形行为。塑性增强是由于W球的作用，它抑制了剪切带的传播并促进了多个剪切带的形成。复合材料的性能对应变速率有明显的依赖性。应变速率越高，材料的强度越高，塑性越大。
The millimetre scale W balls reinforced Zr-base bulk metallic glass composite was prepared using infiltration technique. The compressive deformation behaviours of the composite at two strain rates of 1×10−4s−1and 1×10−2s−1were investigated. The enhanced plasticity is attributed to the effect of W balls, which constrain shear bands propagation and promote the formation of multiple shear bands. The properties of the composite depend evidently on the strain rates. The high strain rate leads to the higher strength and larger plasticity.
