“…Brazing, which is usually defined as a joining method with a molten filler metal and the solid substrates, can offer many advantages over other fusion welding methods such as a relatively low brazing temperature, the possibility of dissimilar materials and complex structures joining, high precision and better joint properties. In recent years, a number of investigations on brazing titanium aluminides have been reported which involve both conventional furnace brazing [ 29 , 30 , 31 ] and infrared brazing [ 14 , 15 , 17 , 32 ]. In general, titanium aluminides are suitable for brazing because most conventional filler metals can wet them well.…”
