| 中文摘要: |
| 目前，新型轻质高温结构材料TiAl合金铸造部件已经进入工业化生产阶段，急需工业级铸造用TiAl母合金的制造技术和评估体系作为支撑。结合了钢铁研究总院铸造TiAl合金工程化研究和应用成果，概述了国内外铸造TiAl合金材料和部件的工程化应用现状，在此基础上，提出了铸造TiAl母合金的化学成分、规格等技术要求，并进一步对比分析了2次自耗熔炼、自耗熔炼+凝壳熔炼、自耗熔炼+凝壳熔炼+自耗熔炼等母合金制备工艺的优缺点，最后提出了工业级铸造TiAl母合金的技术发展方向。 |
| 英文摘要: |
| The new lightweight high-temperature structural material TiAl alloy casting components have entered the industrial production stage. The manufacturing technology and evaluation system of TiAl master alloys are urgently needed for industrial casting. This paper summarized the current engineering application status of cast TiAl alloy materials and components at home and abroad, based on the research and application achievements of Central Iron and Steel Research Institute on the engineering of cast TiAl alloy. On this basis, the technical requirements for chemical composition, specifications, and other aspects of cast TiAl master alloys were proposed, and the advantages and disadvantages of the master alloy preparation processes such as twice consumable melting, consumable melting+shell melting, consumable melting+shell melting+consumable melting were further compared and analyzed. Finally, the technological development direction of industrial cast TiAl master alloys was proposed. |
