中文摘要:
      基于ANSYS有限元软件建立了钒合金电子束熔炼过程的数理模型,对V-4Cr-4Ti合金电子束熔炼过程进行了数值模拟,研究了不同熔炼工艺参数下的熔炼过程温度场分布规律以及熔池形状。研究结果表明:熔炼过程温度场分布及熔池形状受到熔炼功率及扫描半径的影响。随着熔炼功率的增大,熔池最高温度将会线性增大,熔池宽度和深度将会逐渐增大。随着扫描半径的增大,熔池最高温度将会先增大后减小,通过分析获得了V-4Cr-4Ti合金电子束熔炼的最佳工艺参数。实验结果表明,在优化后的工艺条件下,钒合金电子束熔炼铸锭质量得到一定提升。
Numerical Simulation of Electron Beam Melting Vanadium Alloys by Finite Element Method

英文摘要:
      In this article, a mathematical model was developed to investigate the electron beam melting (EBM) process of vanadium alloys. The temperature distribution of molten V-4Cr-4Ti alloy was obtained by using the model. The effects of different parameters of electron beam melting process on the temperature field and the shape of molten pool were studied. The results showed that the temperature field and the shape of molten pool were influenced by the melting power and scanning radius. With the melting power increasing, the max melt temperature increased linearly and the width and depth of molten pool increased gradually. With the scanning radius increasing, the max melt temperature increased first and then reduced. The optimized parameters of refining vanadium were obtained, and the accuracy of the model was validated by the experimental data.
