本文采用水冷铜型铸造法制备了直径为5 mm的Cu46.5Zr48.5Al5块体非晶合金。显微组织观察表明，合金由非晶相和含CuZr马氏体的晶相组成。采用纳米压痕法研究了合金中晶区和非晶相在渐进多点模式下的变形行为。结果表明，非晶相的卸载和随后的再加载h-p曲线可以相互折返。而对于结晶区，在典型的弹性区域，卸载和再加载h-p曲线之间存在明显的滞后回线，表明发生了“应力诱导相变”。这种独特的变形行为的材料也证实了通过使用单轴压缩试验。
In this paper, 5mm diameter Cu46.5Zr48.5Al5bulk metallic glass forming alloys were prepared by water cooled Cu-mould cast. Microstructural observation shows that the alloys consist of amorphous phase and crystalline phase containing CuZr martensite. The deformation behaviors of the crystalline region and amorphous phase in the alloys were studied by means of nanoindentation tests under progressive multicycle mode. The results reveal that the unloading and the subsequent reloading h–p curves for the amorphous phase can retrace each other. While for the crystalline region, an obvious hysteresis loop was found between the unloading and reloading h–p curves in the typically elastic regime, indicating the occurrence of ‘stress-induced phase transformation’. This unique deformation behavior of the material was also confirmed by using uniaxial compression tests.
