TC4钛合金高温热拉伸行为及本构方程研究
Study of Hot Tensile Deformation and Constitutive Equations of TC4 Titanium Alloy
摘要
Abstract
The hot tensile tests of TC4 titanium alloy are done on an electronic universal tensile testing machine RG2000-20 in the range of temperature 850 ℃ ～ 920 ℃ and strain rate 0.000 01 ～ 0.001s-1.Through the test,the true stress-strain curves at different temperature and strain rate are figured out and the influence of the temperature and strain rate on the tensile test curves is analyzed,and then the constitutive equations under the high temperature condition are established based on the improved Hooke Law and Grosman equation.关键词
