It has been reported that the Pt3Al phase has two crystal structures: The high-temperature cubic form of L12 and the low-temperature tetragonal form of the distorted L12 structure D0'c. In this study, the structure of the Pt3Al phase in quaternary Pt-Al-Ir-Nb and ternary Pt-Al-Nb alloys was investigated using scanning electron microscopy (SEM), X-ray diffraction (XRD), differential thermal analysis (DTA), and transmission electron microscopy (TEM) technologies. The structure form was determined to be cubic L12. The stabilization of the L12-Pt3Al structure in room temperature was attributed to the effect of Nb.
