摘要

研究了喷射成形高温合金FGH4095在温度为1010—1140 ℃、应变速率为0.001—10.0 s-1下的热变形行为, 并使用双曲正弦模型建立了喷射成形FGH4095的本构方程. 结果表明: 本构方程预测结果与实验值符合较好, 为喷射成形FGH4095热加工过程的数值模拟提供了较准确的模型.

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.
