摘要
B2-CuZr相增强非晶合金因增强相特殊的“相变诱导塑性”而表现出优于传统增强相的综合力学性能,成为近年来材料领域的研究热点之一。然而原位自生B2-CuZr相的含量、尺寸及其分布难以调控,且铸造过程中易发生共析分解,限制了此类材料的应用范围。通过铸造工艺控制、合金成分调控及后处理等方法可有效解决上述问题。本文将对B2-CuZr相增强非晶复合材料的组织特点、增强机制及复合组织调控方法等方面进行综述,并对其未来发展进行简要展望。
B2-CuZr phase reinforced amorphous matrix composites usually show better mechanical properties than those with conventional reinforcement phases due to their unique“transformation-induced plasticity”phenomenon.However,the volume fraction,size and distribution of in-situ B2-CuZr phase are difficult to control,and B2-CuZr tends to suffer eutectoid decomposition,which restricts the widespread application of these materials.The microstructural optimization can be realized via tailoring the casting parameter,composition and after treatment.The present paper gave a review on the microstructural characterization,reinforcement mechanism and microstructural tailoring methods of B2-CuZr phase reinforced amorphous matrix composites.
