TB17钛合金高温压缩变形行为
|
摘要
通过Gleeble 3800热模拟试验机对TB17钛合金在变形温度860～980℃、应变速率为0.001～1 s~(-1)、最大变形量为70%下高温变形行为进行研究。通过材料参数与真应变之间的关系,利用Arrhenious本构方程关系式和Z参数建立流变应力和变形温度、应变速率和真应变三者之间的本构关系,并对组织进行分析。结果表明:TB17钛合金在应变速率为0.001～0.01 s~(-1)、变形温度为890～980℃下更容易发生连续动态再结晶,而在应变速率为0.1～1 s~(-1)下主要发生不连续动态再结晶;误差分析结果显示计算值与实测值平均相对误差为6%,说明建立的本构关系模型具有较高的准确度。
The high temperature hot deformation behavior of TB17 titanium alloy was studied using Gleeble-3800 thermocompression simulation tester at the temperature of 860-980 ℃,strain rate of 0.001-1 s~(-1) and the deformation degree of 0.7.The deformation behavior and microstructure were studied.By building the relationship between material parameters and true strain,the relationship between flow stress and deformation temperature,strain rate and strain was established by using Arrhenious constitutive equation and Z parameter.The results show that TB17 titanium alloy is more likely to happen continuous dynamic recrystallization at strain rate of 0.001-0.01 s~(-1) and deformation temperature of 890-980 ℃,while discontinuous dynamic recrystallization occur mainly at high strain rate(≥ 0.1 s~(-1)).The error analysis shows that the average relative error between calculated and measured values is 6%.It indicates that the constitutive relation model has higher accuracy.
