摘要：

By treatment of solid Ni or Co with a H-2/TiCl4-gas mixture at sufficient high temperature (T greater than or equal to 900 degrees C) the intermetallic phases TiNi3 and TiCo3, resp., are formed. The conversion grade depends on the H-2/TiCl4-ratio. From the experimentally determined conversion grades and the known thermodynamic data of all other species existing in equilibrium the free enthalpies and the heats of formation of TiN3 and TiCo3 have been calculated (TiNi3: Delta H-f(o)(298) = -133.3 +/- 6 kJ/mol; TiCo3: Delta H-f(o)(298) = -104.7 +/- 6 kJ/mol).
