摘要

利用热模拟试验机,研究了厚度规格1.0 mm 00Cr22Ti冷轧板在900～1000℃等温不同时间退火后组织转变和硬度变化,建立了其再结晶动力学方程,并计算了再结晶激活能Q。结果表明:在不同温度退火时,00Cr22Ti不锈钢的再结晶率随时间呈S型增大;利用Avrami模型进行再结晶动力学模拟,得出了其不同退火温度的Avrami常数n值,并计算出了其再结晶激活能Q=71.11 kJ/mol。
        Microstructure evolution and hardness change of 00 Cr22 Ti ultra-purified ferritic stainless steel cold rolled sheet(1.0 mm thick) after isothermal annealing at 900-1000 ℃ for different time were studied by using a thermal simulation tester, and the recrystallization kinetics equation of the steel was established and its recrystallization activation energy Q was calculated. The results show that when annealed at different temperatures, the recrystallization rate of the 00 Cr22 Ti stainless steel increases with time as S shape. The Avrami constant n value of the steel at different annealing temperatures is obtained by using Avrami model to simulate recrystallization kinetics, and its recrystallization activation energy Q is 71.11 kJ/mol.
