喷射成形FGH4095的热变形特征
Hot deformation behavior of spray formed FGH4095
摘要
Abstract
For the numerical simulation of hot working process of spray-formed FGH4095, the high temperature deformation behavior of spray-formed FGH4095 is studied at different deformation temperatures (1010-1140 ℃) and different strain rates (0.001-10.0 s-1) using Gleeble 3800 thermal simulator. The constitutive equation is established with the sinh model. The calculative results are consistent with the experimental data. It indicates that the accurate material model is provided for the numerical simulation for hot working process of spray-formed FGH4095.关键词
