摘    要:通过对TA10钛合金在电子束冷床炉熔炼过程中Ni、Mo元素的过程分析和理论计算,掌握各元素的挥发机理和挥发动力学,研究TA10合金在电子束冷床炉上的单次熔炼工艺。结果表明:经电子束冷床炉单次熔炼的TA10合金铸锭化学成分均匀,铸锭宏观组织均匀,生产的铸锭经后续加工所得到的产品均满足标准要求。

Abstract: Through the analysis of the process and theoretical calculations for Ni and Mo elements during electron beam cold hearth melting, the element evaporation mechanism and kinetics of volatile were discussed. Single electron beam cold hearth melting technology of TA10 alloy was studied. The results show that the chemical compositions of the TA10 alloy ingot are uniform by electron beam cold hearth melting, the macro homogeneous is good, and the product meets the standards through the subsequent processing.
