B-Mo-Nb alloys, as-cast and annealed at subsolidus temperatures, were experimentally studied by x-ray diffraction technique and scanning electron microscopy with electron probe microanalyses. Temperatures of incipient melting were measured by pyrometry after Pirani and Alterthum. No ternary compound was found in the examined alloys. Based on the experimental data, the B-Mo-Nb phase diagram was constructed for the first time, including liquidus and solidus surface projections and Scheil’s reaction scheme.
