Test Methods and Properties of Powder Metallurgical Materials


Using data on melting points, phase and chemical compositions, lattice constants, and microhardnesses of individual phases and alloys, a constitution diagram has been constructed for the quasibinary eutectic system TiN0.96-TiB2. The system has a eutectic temperature of 2600±40°C and a eutectic composition 40 wt. % TiN0.96 + 60 wt. % TiB2. It is characterized by a negligible intersolubility of the components (up to 3–4 wt. % TiB2 in TiN0.96 and a virtual insolubility of TiN2 in TiB2).
