摘要

采用铜模吸铸法制备了直径为φ3mm的Cu

非晶合金试样（BMGs）

利用X射线衍射（XRD）仪、透射电镜（TEM）、万能材料试验机、同步示差扫描量热仪（DSC）和扫描电镜（SEM）等手段研究了预压缩处理时间对Zr-Cu基非晶合金塑性的影响。结果表明

所制备的合金均为非晶态;随着预压缩处理时间的延长

试样内部的自由体积含量及室温塑性提高

当处理时间为100min时

试样内部的自由体积含量及其室温塑性均达到最优值

继续延长预压缩处理时间

自由体积含量及室温塑性虽有增加

但增加幅度呈下降趋势。

Abstract

amorphous alloy samples（BMGs）with diameter of 3 mm were prepared by copper mold suction casting method.Effects of pre-compression treatment time on plasticity of Zr-Cu based amorphous alloy were investigated by means of X-ray diffraction（XRD）

transmission electron microscope（TEM）

universal testing machine

differential scanning calorimeter（DSC）and scanning electron microscope（SEM）.Experimental results show that the samples prepared exhibit amorphous alloys.With the increase of pre-compression processing time

the free volume content and the room temperature plasticity of the sample are improved

and the treatment time is 100 min

they exhibit the desirable value.Further to increase pre-compression processing time

free volume content and room temperature plasticity of the amorphous are increased with slow tendency.
