抄録

The phase diagram of the Ni–W–B ternary system in the region of less than 50 mol%B was constructed by thermodynamic calculation based on the regular solution approximation. We found three ternary eutectic points and two ternary peritecto-eutectic points as follows:<BR>E₁: L(1622 K, 51.0 mol%Ni-31.6 mol%W-17.4 mol%B)=(Ni)+W+NiW₂B₂<BR>E₂: L(1260 K, 71.0 mol%Ni-7.0 mol%W-22.0 mol%B)=(Ni)+Ni₃B+NiW₂B₂<BR>E₃: L(1291 K, 65.4 mol%Ni-4.8 mol%W-29.8 mol%B)=Ni₂B+Ni₃B+NiW₂B₂<BR>P₁: L(2115 K, 23.8 mol%Ni-43.1 mol%W-33.1 mol%B)+WB=W₂B+NiW₂B₂<BR>P₂: L(1657 K, 48.9 mol%Ni-33.1 mol%W-18.0 mol%B)+W₂B=W+NiW₂B₂<BR>The calculated phase diagram is expected to be useful for the development of new Ni-based heat-, corrosion- and wear-resistance alloys strengthened by NiW₂B₂.
