• Revised phase diagram for the Pt–Ti system from 30 to 60 at.% platinum
  作者：T Biggs、L.A Cornish、M.J Witcomb、M.B Cortie

  DOI：10.1016/j.jallcom.2003.12.001

  日期：2004.7

  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 beta-TiPt and Ti3Pt at 1205+/-10 degreesC. The eutectic reaction between Ti3Pt and beta-TiPt was found to be at similar to35 at.% Pt and 1424+/-10degreesC, and the Ti3Pt phase melted at circa 1500degreesC. The other phase boundaries agreed with the published literature, except that a slightly wider range was found at 1200degreesC for beta-TiPt. (C) 2004 Elsevier B.V. All rights reserved.
• Ti–Pt intermetallic compound catalysts more active than Pt for hydrogen dissociation and ethylene hydrogenation

  The intermetallic compound, TiPt3, showed much higher catalytic activity than pure Pt catalyst for H2–D2 equilibration and ethylene hydrogenation, whereas Ti3Pt only catalyzed the former reaction with a similar activity to TiPt3.
