Aufbau und Schmelzverhalten von Nickel-Kupfer-Bor und Nickel-Kupfer-Silicium Legierungen

Within the group of boride and suicide containing hard alloys, those based on copper have recently found increasing interest as wear-resisting stratification and high-temperature structural materials. For the development of the best alloy, the phase conditions in the systems nickel-copper-boron and nickel-copper-silicon were elucidated from the isothermal profiles at 700°. Melting behaviours (important from a practical point of view) in the area of low metalloid contents are presented in the cases of (Ni-Cu-B) mixed crystals, Ni₃B alloy, as well as Ni-Cu-10 atomic % B and Ni-Cu-10 atomic % Si.
