粉末冶金Mo-14Re合金热变形行为及微观组织演变OA北大核心CSTPCD
Thermal deformation behavior and microstructure evolution of Mo-14Re alloys prepared by powder metallurgy
通过Gleeble1500热模拟试验机对粉末冶金法制备的Mo-14Re合金进行了恒应变速率压缩实验,分析了变形温度(1100～1400 ℃)和应变速率(0.100～0.001 s-1)对流变应力及组织演变的影响,并采用双曲正弦型Arrhenius模型建立了Mo-14Re合金的本构方程.结果表明:随着变形温度升高或者应变速率降低,粉末冶金Mo-14Re合金在热变形过程的流变应力也随之减小,真应力-真应变曲线表现出明显的加工硬化和动态软化现象.…查看全部>>
The constant strain rate compression experiment of powder metallurgy Mo-14Re alloys was carried out by Gleeble 1500 thermal simulation tester.The effects of deformation temperature(1100～1400 ℃)and strain rate(0.100～0.001 s-1)on the flow stress and microstructure evolution were analyzed.The constitutive equation of Mo-14Re alloys was established by hyperbolic sinusoidal Arrhenius model.The results show that,the flow stress of powder metallurgy Mo-14Re alloys …查看全部>>
