针对钛合金压气机盘的等温流变成形过程 ,应用有限元数值模拟方法 ,对热加工规范许可的某一成形温度和不同应变速率下的流变成形过程进行了分析和比较。模拟结果包括一系列人机交互自动生成的流变过程图、等效应变场、挤压力曲线及等温度场等 ,从数值模拟“实验”的角度 ,对热流变成形过程进行了不可逆过程热力学分析 ,并对等温流变成形件进行了低倍流线、金相组织、力学性能等的检测 Aiming at the isothermal rheological forming process of titanium alloy compressor disk, the finite element method was used to analyze and compare the rheological forming process at a certain forming temperature and different strain rate permitted by the hot working specification. The simulation results include a series of rheological process maps, equivalent strain fields, extrusion pressure curves and isothermal temperature fields generated automatically by human-computer interaction. From the numerical simulation “experiment” perspective, the irreversible process of the thermoforming process Thermodynamic analysis, and isotherm rheo-shaped parts were low-flow lines, microstructure, mechanical properties of the detection
