ResumoThe phase diagram of the Ni–Mo–B ternary system in the region of less than 50 mol%B was constructed by thermodynamic calculation. We found three ternary eutectic points and three ternary peritecto-eutectic points as follows: E1: L(1365 K, 71.5 mol%Ni–6.0 mol%Mo–22.5 mol%B)=(Ni)+Ni3B+NiMo2B2. E2: L(1355 K, 62.5 mol%Ni–2.5 mol%Mo–30.5 mol%B)=Ni3B+Ni2B+NiMo2B2. E3: L(1445 K, 42.0 mol%Ni–30.6 mol%Mo–10.3 mol%B)=(Ni)+NiMo+NiMo2B2. P1: L(1812 K, 34.9 mol%Ni–42.3 mol%Mo–22.8 mol%B)+MoB=Mo2B+NiMo2B2. P2: L(1633 K, 42.3 mol%Ni–40.4 mol%Mo–17.3 mol%B)+Mo=Mo2B+NiMo2B2. P3: L(1478 K, 53.5 mol%Ni–33.7 mol%Mo–12.8 mol%B)+Mo=NiMo+NiMo2B2.
