系统研究了Cu51.5Zr48.5形状记忆金属玻璃复合材料的单轴压缩行为，找出了控制其变形和断裂的显着微观机制。在显微结构上，发现在这些玻璃中形成的CuZr析出物的粒度和体积分数对冷却速度和铸造环境高度敏感。塑性流动是由材料中CuZr颗粒的马氏体相变引起的，另外，由于微裂纹和裂纹偏转导致了它们的非弹性，从而进一步提高了塑性和抗断性能。
The uniaxial compression behavior of Cu51.5Zr48.5shape-memory metallic-glass composites was systematically studied, from the perspective of discerning the salient micro-mechanisms controlling their deformation and fracture. Microstructurally, it was found that the particle size and volume fraction of CuZr precipitates formed in these glasses were highly sensitive to cooling rate and casting environment. Plastic flow was induced by a martensitic transformation of the CuZr particles in these materials, with additional contributions to their inelasticity arising from microcracking and crack deflection, which further served to promote ductility and resist fracture.
