将TA11合金的微观组织模型写入DEFORM-3D软件的用户子程序中,使其具备了对TA11合金热成形过程中微观组织的预测及模拟功能,并通过对圆柱体镦粗过程的模拟验证了程序的可靠性。以TA11合金叶片的挤杆过程为研究对象,对其微观组织变化进行数值模拟,研究了变形工艺参数对变形过程中微观组织变化的影响。结果表明,合适的变形速度、变形温度和压下量可以使晶粒细化,组织分布均匀,从而提高锻件的力学性能。
The microstructure model of TA11 alloy was written into the user subroutine of DEFORM-3D software, which made it have the function of predicting and simulating the microstructure of TA11 alloy during thermoforming. Through the simulation of cylinder upsetting process Program reliability. TA11 alloy blade squeeze bar process as the research object, its microstructure changes were numerically simulated, and the effects of deformation parameters on the microstructural changes in the deformation process were studied. The results show that the appropriate deformation speed, deformation temperature and reduction can make the grain refinement and the distribution of the microstructure to improve the mechanical properties of the forging.
