Abstract
Phase diagram of the Y-B system and isothermal sections of the Y-Fe-B system at 600 and 800 °C were investigated using X-ray diffraction (XRD), electron probe microanalysis (EPMA) and differential scanning calorimetry (DSC) on the annealed alloys. In the Y-B system, temperature of L↔(αY)+YB2 was determined to be 1294 °C. YB6 was confirmed to be a stoichiometric compound at 1000 °C. For the isothermal section of the Y-Fe-B system at 600 °C, five ternary compounds (τ1-τ4, τ6) and 10 three-phase regions were observed. But there were six ternary compounds (τ1-τ6) and 18 three-phase regions in the isothermal section at 800 °C. Ternary phases were measured to be stoichiometric compounds and the measured solubility of the third element in the binary phases was mostly below 0.5 at.% at both 600 and 800 °C.
