摘要
简述了铸造钛合金及TiAl合金的特点及在国内外航空领域的应用。根据我国钛合金领域专利申请情况分析了铸造钛合金技术在近30年的变化,特别是在航空领域的变化。随着航空制造技术的发展和高性能飞机的需求,钛合金铸件正向大型、整体和复杂化变化,TiAl合金铸件的发展将大大提高航空钛合金的使用温度。而航空领域的钛合金铸造技术将不再是单一的熔模精密铸造,将融合铸造模拟仿真技术和增材制造技术的优势,采取复合式发展的道路,以提高其整体精铸水平和生产效率。
The application and feature of Ti alloy and TiAl alloy for aviation at home and abroad were briefly introduced.According to the patent application status in Ti alloy field,the development of Ti alloy casting technology was analyzed in the recent thirty years,especially the transformation in aviation.Along with the development of aeronautional manufacturing technology and demand of high performance aircraft,Ti alloy casting is changing towards to be large,integral and complicated,and the evolution of TiAl alloy casting increases the operating temperature of the Ti alloy casting for aviation.Moreover,the Ti alloy forming technology is no longer a single investment casting.Combining with the advantages of casting simulation technology and additive manufacturing technology,it adopts a compound way of development in order to increase its integral casting level and productive efficiency.
