研究了(Cu50Zr50)92Al8非晶合金在过冷液相区中,经过牛顿流变和非牛顿流变后的等温晶化行为及其对该合金力学性能的影响。结果表明,牛顿型流变对(Cu50Zr50)92Al8非晶合金的结构没有明显的影响;而非牛顿流变对该非晶的显微结构及其等温晶化行为有显著影响:非牛顿流变促进了(Cu50Zr50)92Al8非晶合金的晶化,其主要晶化相为体心立方结构的CuZr相(B2相)和CuZr马氏体相;经非牛顿流变及真空热处理试样,在室温压缩过程中,应力诱发了部分B2相的马氏体相变,从而使其在室温下表现出超弹性,当预塑性应变量为8%时,其总可回复应变为5%左右。 The isothermal crystallization behavior of (Cu50Zr50) 92Al8 amorphous alloy in supercooled liquid region after Newtonian rheology and non-Newtonian rheological behavior was investigated and its effect on the mechanical properties of the alloy was investigated. The results show that Newtonian rheological behavior has no significant effect on the structure of (Cu50Zr50) 92Al8 amorphous alloy. Non-Newtonian rheology has significant effect on the microstructure and isothermal crystallization behavior of the amorphous alloy. Non-Newtonian rheology The (Cu50Zr50) 92Al8 amorphous alloy is crystallized. The main crystallized phases are CuZr phase (B2 phase) and CuZr martensite phase with cubic structure. After non-Newtonian rheological and vacuum heat treatment, the samples are compressed at room temperature In the process, the stress induces a martensitic transformation of some of the B2 phases so that it exhibits superelasticity at room temperature. When the amount of preplastic deformation is 8%, the total recoverable strain is about 5%.
