中文摘要：

有作为加强，肉眼可见地显示出的紧张变硬行为在变丑期间由 martensitic 转变由于粘性导致了的奥氏体 B2 阶段的体积金属性的玻璃(BMG ) composites。在增强阶段和基于 CuZr 的 BMG composites 的单轴的压缩性质的 B2-CuZr 的特征之间的关系被学习。composites 被发现取决于不仅增强的阶段而且非结晶的矩阵的这些 BMG 的机械性质，和收益和破裂力量能被混合原则的规则粗略地估计。增强的 B2-CuZr 阶段的分发与水晶的阶段的类似的体积部分甚至为 composites 在压缩粘性上有重要影响。

英文摘要：

Bulk metallic glass （BMG） composites with the austenite B2 phase as reinforcement macroscopically showed strain hardening behavior due to the plasticity induced by martensitic transformation during deformation. Relationship between characteristics of the B2-CuZr reinforcing phase and uniaxial compressive properties of CuZr-based BMG composites was studied. Mechanical properties of these BMG composites were found to depend on not only the reinforced phases but also the amorphous matrix,and the yield and fracture strength can be roughly estimated by the rule of mixture principle. Distribution of the reinforced B2-CuZr phase has an important impact on the compressive plasticity even for the composites with a similar volume fraction of the crystalline phase.
