摘要(Abstract)：

选择400、600、743、753、873和973 K,进行30 min和3 h的等温退火,用XRD、万能试验机和SEM研究退火处理对Cu基块状非晶合金压缩性能的影响。结果表明,随着退火时间的延长,Cu基块状非晶合金的起始晶化温度逐渐降低;试样经过30 min和3 h的退火处理后,其压缩曲线均为线弹性,没有明显的非弹性屈服过程;在600、743和753 K经过30 min的退火处理后的压缩强度的变化趋势为降低-升高-降低的模式,与经过3 h退火处理的压缩强度的变化趋势相反,对压缩强度的变化原因进行了初步分析;Cu基块状非晶合金在743 K退火30 min后的压缩性能最好,压缩强度达到2138 MPa。
