| Abstract: | Ti-Al intermetallic compound is the most potential structural materials with light weight and high temperature resistance for aircraft engine,and has the characteristics of low density,low thermal expansion rate,high heat conductivity and high heat resistance temperature. It may replace existing titanium alloy and nickel base super alloy material and become low or high temperature end components manufacturing materials for aero-engine compressor. The properties and characteristics of Ti-Al intermetallic compounds are briefly introduced. Research and application of welding technology of typical Ti-Al intermetallic compound,such as Ti3Al,TiAl and Ti2AlNb are summarized. Finally,the high quality welding technology and applications of Ti-Al intermetallic compounds in the field of aero-engines are summarized and expected. |
