Topic: High Temperature Platinum Group Metals:
      Fundamental Research & Applications

Speaker: Prof. Dr. Yoko Yamabe-Mitarai

  National Institute for Materials Science, Tsukuba, Japan

Time: 10:30~11:30, (Wed.) 30, June, 2010

Venue: Room 403, R&D building, IMR CAS

Welcome to attend!

Abstract:

Platinum group metals (PGM) are widely used as catalysts in automotive industry, chemical industry and petroleum refinery, as well as high temperature structural materials. Rh-containing Pt alloys strengthened with oxide dispersion are used to melt liquid crystal displays in glass industry. Ir, one of PGM, is used as crucibles to grow single crystal of oxide for optics and optoelectronics device because its melting temperature is 2716 K. Here, some fundamental data about the mechanical properties, phase stability and oxidation behavior of PGM, in particular, Ir alloys will be presented. Potential of Ir alloys as high temperature structural materials will be presented. New application of PGM for ultra-high temperature shape memory alloys (Martensitic transformation occurs above 1273 K) will be also introduced.
