Properties of Phases and Alloys of the Mo–Ni–B System in the Ni–MoNi–Mo2NiB2–Ni2B Region

For alloys of the Mo–Ni–B system annealed at subsolidus temperatures (and some as-cast alloys) in the Ni–MoNi–Mo 2 NiB 2 –Ni 2 B 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, f...

Description
Summary:For alloys of the Mo–Ni–B system annealed at subsolidus temperatures (and some as-cast alloys) in the Ni–MoNi–Mo 2 NiB 2 –Ni 2 B 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°C. It is shown that this alloy has low plasticity but high heat resistance up to 600°C.
