摘要 通过THERMECMASTOR-Z热模拟机对成分(%)为0.009C、0.047Ti的Ti-IF钢进行750~850℃变形速率1~70s^-1的单道次压缩变形试验。从不同变形温度和速度下所得应力-应变曲线表明,随变形速率和应变的增加,流动应力增大,但在实验温度范围内,变形温度对流动应力的影响不显著。该Ti—IF钢的Zener-Hollomon参数Z与变形速率ε和变形温度T的关系为:Z=εexp(42150/T)。 The single pass reduction deformation experiments of a Ti-IF steel (0. 009C, 0.047Ti) at 750 - 850 ℃ with strain rate of deformation 1 -70 s^-1 have been carried out by THERMECMASTOR-Z thermal simulation machine. Based on obtained stress - strain curves with different temperature and strain rate of deformation, it showed that with increasing speed and strain of deformation, the flowing stress increased, while at experimental temperature range the effect of deformation temperature on flowing stress was not obvious. The relation between Zener-Hollomon parameter Z of the Ti-IF steel and strain rate ε and temperature T of deformation was Z = ε exp(42 150/T).
