The lattice constants of alloys in the Mo-Ni-B system increase with Mo content, and the 13Mo-81Ni-6B (at.%) hypoeutectic alloy exhibits low plasticity but high heat resistance up to 600 degrees C within the temperature range of 20-700 degrees C.
For alloys of the Mo-Ni-B system annealed at subsolidus temperatures (and some as-cast alloys) in the Ni-MoNi-Mo2NiB2-Ni2B region, we study the dependence of lattice constants of the phases on their composition and analyze the obtained values of Vickers microhardness. It is established that, for most phases, the lattice constants increase with the Mo content in these phases. The strength and plasticity of the 13Mo-81Ni-6B (at.%) hypoeutectic alloy are determined within the temperature range 20-700 degrees C. It is shown that this alloy has low plasticity but high heat resistance up to 600 degrees C.
