摘要

按照Gleeble 1500D机热模拟试验结果

通过回归分析得出Ti-Nb IF(无间隙原子)钢(%:0.005C、0.055Al、0.01Nb、0.08Ti)在铁素体温度区(840～780℃)流变应力峰值σ

与Zener-Hollomon参数Z(T

ε)之间的解析表达式;利用铁素体区变形的功率耗散图和加工失稳图建立了该钢的热加工图

获得其加工安全区和失稳区。结果表明

变形温度800～825℃

应变速率0.02～0.002 s

-1

区域为Ti-Nb IF钢铁素体区热加工安全区域。

Abstract

According to hot simulation test results by Gleeble 1500D machine

the analytic expression between flow peak stress σ

and Zener-Hollomon factor Z ( T

ε ) for Ti-Nb IF ( interstitial atom free) steel (0. 005C

0. 055Al

0. 01 Nb

0. 08Ti) in ferrite temperature area (840 - 780 °C ) has been obtained ； and the hot processing map for the steel has been established by using power dissipation map and working instability map for test steel in ferrite deformation area to get its processing safety area and instability area. Results showed that the area with deformation temperature 800 ~ 825 °C and strain rate 0. 02 ~ 0. 002 s

-1

was processing safety ferrite area for hot workability of the Ti-Nb IF steel.
