摘要

本文借助金相显微镜, XRD, SEM和DSC等手段对Cu75.15Al24.85合金经15 GPa压力, 750℃保温15 min处理前后的组织结构进行了分析,并用电阻率测试仪对合金的电阻率进行测试,以此探讨了高压处理对Cu75.15Al24.85合金组织与电阻率的影响. 结果表明:高压处理能细化Cu75.15Al24.85合金的组织,增大合金的电阻率, 当压力为3 GPa时,该合金获得的组织最细小,电阻率最大.

Abstract

The microstructures of Cu75.15Al24.85 alloy before and after treatment at 15 GPa pressure and 750℃ for 15 min are analyzed by optical metallograph, X-ray diffraction, scanning electron microscopy and differential scanning calorimeter, and its resistivity is also obtained through resistivity measuring instrument. According to the obtained results, the effects of high pressure treatment on the microstructure and resistivity are investigated. The results show that high pressure treatment can refine the microstructure, and increase the resistivity of the alloy. When the pressure is 3 GPa, the refinement is more remarkable and the resistivity reaches a maximal value.
