Revised phase diagram for the Pt-Ti system from 30 to 60 at.% platinum

Description

Alloys of the Ti-Pt system between 30 and 61 at.% Pt were studied using metallography with optical and scanning electron microscopy (SEM), X-ray diffraction (XRD), and differential thermal analysis (DTA). A phase of nominal composition Ti4Pt3, in the range 41.7-43.4 at.% Pt was found in samples containing between 30 and 47 at.% Pt, and was apparently formed by a peritectoid reaction between β-TiPt and Ti3Pt at 1205±10 deg. C. The eutectic reaction between Ti3Pt and β-TiPt was found to be at ∼35 at.% Pt and 1424±10 deg. C, and the Ti3Pt phase melted at circa 1500 deg. C. The other phase boundaries agreed with the published literature, except that a slightly wider range was found at 1200 deg. C for β-TiPt
