摘      要：Au-Pd-Zr ternary alloy phase diagram at 25℃ was calculated by Panda phase calculation software,and the thermodynamic data were based on three binary alloy phase diagrams：Pd-Au,Au-Zr,and *** composition points in the ternary phase diagram were selected to predict the precipitation ***（32Au-32Pd-36Zr） of the five composition points in ternary phase diagram was chosen to verify the correctness of the phase diagram calculation and the precipitation order by scanning electron microscopy（SEM）,energy dispersive spectroscopy（EDS）,and X-ray diffraction（XRD）.The unknown phase in XRD patterns was predicated by EDS and materials studio（MS） *** experimental results show that there are seven key ternary reactions points and 17 phase regions in all isothermal sections at 25℃.The thermodynamic process and microstructure for the alloy phase can be described in order according to the vertical section in phase *** phase compositions of the chosen one point are consistent with calculation *** unknown phase in XRD patterns should be Zr_2AuPd by the first principle X-ray simulation.
