Structure and phase composition of Ti-Ni-Cu alloys

Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

Alloying with 4–10% Cu has an inoculating action on the structure of the eutectic titanium-nickel alloy, resulting in its refinement and a redistribution of its constituents, improves the wetting of diamond by the alloy, and lowers the latter's melting point. This opens up the possibility of using such materials in the formulation of diamond-containing composites. The addition of 20–30% Cu results in the formation of three-phase alloys of intermetallic character, which are characterized by a low melting point (930°C), a finegrained structure, and satisfactory adhesion to diamond, but also by low strength and ductility.
