Numerical Simulation of Hot Isostatic Pressing Deformation of ZTC4 Alloy Based on ABAQUS
Thermal isostatic pressure temperature field solver was independently developed based on ABAQUS plat-form,and the temperature field data was loaded into the ABAQUS stress field model as boundary conditions through programming interface to establish the sequential thermodynamic coupling model during hot isostatic pressure process.In order to verify the accuracy,hot isostatic pressing simulation was conducted and validated,and effects of hot iso-static pressing temperature on defect closure of ZTC4 alloy castings were investigated.The results reveal that the size error between simulated and experimental results is less than 5%,indicating that 915℃ is the satisfied temperature for hot isostatic pressing of ZTC4 alloy castings.
