摘要：
This study investigates the phase equilibria of the Al-Mo-Hf ternary system at 400 degrees C and 600 degrees C using X-ray diffraction (XRD) and electron probe microanalysis (EPMA/WDS) techniques. Seven three-phase and five two-phase regions were identified at 400 degrees C, while eight three-phase and four two-phase regions were identified at 600 degrees C. Despite variations in the solid solubility ranges of certain compounds, the distribution of phase zones in the isothermal cross-section remained consistent at both temperatures. Using the experimental results and logical deductions, isothermal cross-sections were constructed for the Al-Mo-Hf ternary system at 600 degrees C and 400 degrees C.
