Aeronautical Cast Ti Alloy and Forming Technology Development

Abstract

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.
