| 摘 要： | 利用铜模铸造法获得了直径为2 mm的Ti35Zr30Be27.5Cu7.5块体非晶合金。采用X射线衍射(XRD)、扫描电镜(SEM)、差氏扫描量热仪(DSC)及压缩试验等方法研究了非晶合金的相结构、显微组织和热稳定性,以及热处理对其压缩强度及塑性的影响。结果表明:在553和583 K温度下分别保温5 h后,实验合金仍保持为非晶态;在613 K保温1 h后,有晶化相出现。Ti35Zr30Be27.5 Cu7.5非晶合金在583 K下保温1 h后其塑性变形量达到了6.57%,较热处理前提高了1倍,且保持了热处理前的强度,屈服强度和抗压强度分别为1921 MPa,2169 MPa。随着热处理温度的提高,非晶相含量减少,合金断裂强度、塑性变形量随之降低;同时合金断裂方式由韧性断裂转变为脆性断裂。 |
