Brazing of nickel, ferrite and titanium-aluminum intermetallics

Intermetallics have many metallic characteristics, including luster, and electrical and thermal conductivity. Ordered intermetallic structural materials have recently been the focus of many investigations. The physical and brazing properties of Ni-Al system intermetallics, Fe-Al intermetallics and Ti-Al intermetallics are presented in this chapter, including brazing methods, joint microstructure and corresponding mechanical strengths. The suitability of a variety of brazing filler metals for Ti-Al intermetallics is also discussed, and an extensive comparison is made between the brazing of traditional materials and those including more than three intermetallics.
