摘要: 在Gleeble-3500D热模拟机上采用单道次等温压缩试验,系统研究了GH4169合金在变形温度为900¹ 150℃、应变速率为0.01¹0 s^-1、变形量为10%⁷0%条件下的热变形行为,通过绘制流变应力曲线和显微组织观察,分析了热变形参数对GH4169合金流变应力、峰值应力和发生动态再结晶的影响,并建立了GH4169合金的本构关系模型。

Abstract: The hot deformation behavior of GH4169 alloy were investigated by single-pass isothermal compression tests with Gleeble-3500 D simulated machine. The investigated variable included the deformation temperature ranging from 900 ℃ to 1 150 ℃,strain rate ranging from 0.01 s^-1 to 10 s^-1 and the deformation degree ranging from 10 % to 70 %.By the resulted flow stress curve and microscopic observation,the influence of thermodynamic parameters on the flow stress,peak stress and dynamic recrystallization of GH4169 alloy was analyzed,and the constitutive relation model of GH4169 alloy was established.
