Abstract

Oxidation- and corrosion-resistant high-temperature alloy based on an intermetallic compound of the chromium silicide type, having the following composition: Si = 23 - 27 atom %, Mo = 5 - 20 atom %, W = 1 - 3 atom %, B = 0 - 1 atom %, Cr remainder The alloy has at least 90% by volume, based on the totality of intermetallic phases, of Cr3Si and Mo3Si. <IMAGE>
