    摘要:

    對(duì)Zr57Cu15．4Ni12．6Al10Nb5塊體非晶合金進(jìn)行了等溫?zé)崽幚?，用X射線衍射儀、掃描電鏡、顯微硬度計(jì)與壓縮試驗(yàn)機(jī)研究了不同溫度下的等溫?zé)崽幚砗蠛辖鸬慕M織結(jié)構(gòu)變化、硬度變化與壓縮性能變化。該非晶合金出現(xiàn)晶化的溫度隨熱處理時(shí)間的增長而降低。在熱處理時(shí)間相同的條件下，隨熱處理溫度升高，合金的顯微硬度有增大趨勢(shì)。當(dāng)非晶合金出現(xiàn)相分離或晶化時(shí)，其抗壓縮強(qiáng)度將急劇下降，斷裂方式由非晶態(tài)的斷裂方式向晶態(tài)的斷裂方式轉(zhuǎn)變。

    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.
