| 摘 要： | 对Zr57Cu15．4Ni12．6Al10Nb5块体非晶合金进行了等温热处理，用X射线衍射仪、扫描电镜、显微硬度计与压缩试验机研究了不同温度下的等温热处理后合金的组织结构变化、硬度变化与压缩性能变化。该非晶合金出现晶化的温度随热处理时间的增长而降低。在热处理时间相同的条件下，随热处理温度升高，合金的显微硬度有增大趋势。当非晶合金出现相分离或晶化时，其抗压缩强度将急剧下降，断裂方式由非晶态的断裂方式向晶态的断裂方式转变。

| Abstract: | The change of microstructure and its influences on the micro-hardness and compression properties of Zr57Cu15.4Ni12.6Al10Nb5 bulk amorphous alloy with isothermal heat treatment have been studied by X-ray diffractometer, scanning electronic microscope, micro-hardness tester and compression experiment. It has been found that as the heating time increases, the crystallization temperature of the amorphous alloy will decrease. The phase decomposition and/or partial crystallization will cause the micro-hardness to increase and the compression strength to decrease rapidly, and make the fracture mode of amorphous alloys changing to that of crystalline alloys. |
