Abstract:
利用Gleeble-1500热模拟试验机对10Cr12Ni3Mo2VN钢进行压缩实验,研究了变形温度为850~1200℃,应变速率为0.01~10s-1条件下的热变形行为.结果表明,随变形温度升高和应变速率降低,再结晶晶粒尺寸增加.变形温度1200℃,经60%压缩变形后,应变速率较高时再结晶晶粒呈等轴状,应变速率较低时出现混晶.通过传统直线拟合方法和Levenberg-Marquardt算法分别建立了热变形双曲正弦本构方程,2种方法建立的本构方程均具有较高预测精度.采用Levenberg-Marquardt算法可以一次性求解所有材料参数,求解步骤简单,结果可信.利用加工硬化率-应力(q-s)曲线,通过二次求导,准确测得临界应变,并建立了临界应变、峰值应变与Zener-Hollomon因子(Z因子)之间的关系方程.
