| 摘 要： | 基于热模拟压缩试验数据,通过共线性诊断、变量筛选、回归分析等过程,建立了置氢Ti600合金热变形的本构关系.结果表明:回归计算值与试验值吻合较好,所建立的本构关系能够描述置氢Ti600合金热变形过程中应变、应变速率、变形温度对流变应力的影响规律.

Constitutive Relationship for Hot Deformation of Ti600 Alloy After Hydrogenation |
| |
| Abstract: | Based on hot compression experimental data,the constitutive relationship of Ti600 alloy after hydrogenation is established through the process of diagnosis of colinearity,selection of variables and regression analysis.The results show that computed values agree well with the experimental ones,and the influence of strain,strain rate and deformation temperature on flow stress are acquired in hot deformation process of Ti600 alloy after hydrogenation. |
