Abstract
Platinum alloys with analogous microstructures to the Ni-base superalloys,
but with higher melting temperatures. were investigated. In a preliminary i
nvestigation, ternary Pt-X-Z compositions were selected to yield two-phase
microstructures consisting of (Pt) and Pt3X, where (Pt) has an fee structur
e and ideally, Pt3X, an ordered fee (LI2) structure. The alloys were ranked
in terms of their microstructures, oxidation resistance, room-temperature
hardness and resistance to cracking at room temperature. It was found that
alloys based on Pt-Al-Z have potential based on their superior environmenta
l and mechanical properties. (C) 2001 Published by Elsevier Science B.V.
