Title: Corrosion-resistant alloy, preparation process and article made from the alloy

Abstract: The invention relates to a Cr.sub.2 O.sub.3 -forming alloy that is resistant to oxidization and/or corrosion at high temperature, especially by glass, characterized in that it contains, in dispersion within its matrix, chromium oxide Cr.sub.2 O.sub.3, or a precursor of this oxide. This alloy can be prepared by powder metallurgy using a process of hot consolidation of metallic powders, in particular by sintering. The alloy is especially suitable for articles which are to be used in a high-temperature oxidizing or corrosive environment.
