摘    要:介绍温度场模拟的传热学原理、初始条件和边界条件;基于体视学方法建立相变潜热转换为等效热容的定量模型,边界条件采用动态表面换热系数,利用商业有限元软件对TB6钛合金降温的三维温度场进行模拟。结果表明:模拟的温度值与实际温度值吻合较好,该数学模型为合金热处理工艺的制定提供了理论依据。

Abstract: Heat transfer theory, the initial conditions and boundary conditions were pointed out briefly. A quantitative modeling of latent heat converting to equivalent heat capacity was established on stereology, and three-dimensional cooling temperature field was simulated by the dynamic heat transfer coefficient. The results show that the simulation temperature fits the actual temperature. The model provides a theoretical basis of heat treatment for other types of alloys.
