| 摘 要： | 研究了在不同时效温度下,时效时间对Cu-Te-Cr合金力学性能和电学性能的影响.利用扫描电镜和能谱仪分析了析出相的形貌、组成及其分布.研究表明,随着时效时间的延长,合金硬度和导电率都先快速上升,然后缓慢下降,出现一个类似峰值点.且温度越高,达到峰值所需的时间越短;随着Te含量的增加,合金硬度减小,而导电率则相对提高.这是由于随时效时间的延长和时效温度的提高,合金发生晶粒长大和第二相析出、从而提高合金硬度和导电率;随时效的进一步进行,部分第二相发生重溶,晶粒进一步长大,合金硬度和导电率缓慢下降. |

| Abstract: | Effect of aging time on the mechanical and electrical properties of Cu-Te-Cr alloys was studied at different temperature.SEM and EDS were used to analyze the morphologies and composition of precipitations.The results showed that with the aging time being longer,both hardness and conductivity of the alloys increase rapidly originally,and then decrease,reaching a peak at a certain time which reduces when the aging temperature increase.With more content of Te adding,the hardness of Cu-Te-Cr alloy drops,while i... |
