TINI-H SYSTEM AT ELEVATED HYDROGEN PRESSURES

The TiNi-H system was studied ar pressures 9.1-15 MPa and temperatures 20-450 degrees C. The most hydrogen-rich compositions obtained at 20 degrees C are TiNiH10 at 10 MPa and TiNiH15 at 15 MPa. The system cont ains no two-phase regions. Sorption isotherms for the Ti2Ni-H and TiNi 3-H systems were measured at hydrogen pressures up to 8.5 and 9.5 MPa, respectively. The hydrogen sorption behavior of TiNiHx differs from t hat of conventional hydrides of metals and alloys.
