Solidus Surface of the Mo–Ni–B System

Аннотация

The Mo–Ni–B alloys with a boron content ca.41 at % were prepared by arc melting, annealed at subsolidus temperatures and studied by X-Ray diffraction method, differential thermal analysis and SEM/EPMA microscopy, and the incipient melting temperatures were measured by the Pirani-Alterthum technique. Based on the authors’ experimental data and in view of the data published elsewhere, the partial solidus surface projection has been constructed for the first time for the Mo–Ni–B system in the region Mo–MoB_1.0–NiB_∼0.8–Ni.
