摘要/Abstract

摘要： 采用等温热压缩实验研究了15CrMo合金钢在温度900~1 100 ℃,应变速率0.01~1 s^－1条件下的热变形行为,获得该合金在高温条件下的真应力-真应变曲线,并构建了适应于15CrMo合金流变曲线的修正型Hansel-Spittel本构模型,修正后模型的相对误差仅为2.82%;基于修正型本构模型绘制了应变为0.1~0.6的热加工图.根据热加工图,得到15CrMo合金钢的最佳热加工温度为900~1 025 ℃,最佳应变速率为0.01~0.055 s^－1.

Abstract: The thermal deformation behavior of 15CrMo alloy steel was investigated through isothermal hot compression tests conducted at temperatures ranging from 900 ℃ to 1 100 ℃, and strain rates ranging from 0.01 s^－1 to 1 s^－1 were examined. The true stress-strain curves of the alloy under high-temperature conditions were obtained, and a modified Hansel-Spittel constitutive model adapted for the rheological behavior of 15CrMo alloy was developed. The relative error of the modified model was only 2.82%. Based on the modified constitutive model, hot processing maps are constructed for strains ranging from 0.1 to0.6. According to these maps, the optimal hot processing temperature range for 15CrMo alloy steel is 900 ℃ to 1 025 ℃, with an optimal strain rate range of 0.01 s^－1 to 0.055 s^－1.
