Phase Equilibria in the Nb-Fe-Cr-Si System. -The new quaternary phase Nb 6.6 Fe 1.4 Cr 4 Si 8 is obtained at 1473 K. The crystal structure is of a new type derived from the Cr 11 Ge 8 -type structure (space group Pnma, Z = 4). The existence of Nb 2 Cr 3 Si 3 at 1523 K is confirmed. It crystallizes i
The effect of an electric of field on the combustion synthesis of MoSi2-xNb (0 ~t 0.45 and y >~ 0.15 can only be synthesized in the presence of a field. Although, in the absence of a field, the system with x = 0.45 and y = 0.15 can sustain a non-steady combustion wave, the reaction is not complete a
