Interaction at the interface between Si3N4 and Ni-Cr alloys at 1125 DegC has been investigated. The internal nitridation of Ni-Cr alloys after annealing in contact with dense Si3N4, due to a high N2-pressure at the interface, was found. The isothermal section of the Ni-Cr-Si system at 900 DegC was detd. by using diffusion couples together with equilibrated alloys. The same isothermal section, as well as the activity of nitrogen in the Ni-Cr alloys was calcd. with aid of the Thermo-Calc databank system. [on SciFinder (R)]
