Abstract
An alloy based on a silicide containing at least chromium and molybdenum contains the following constituents in atomic percent: chromium 41-55, molybdenum 13-35 and silicon 25-35, or chromium 35-55, molybdenum 13-35, silicon 13-35, yttrium 0.001-0.3, and/or tungsten 0.001-10. This alloy is distinguished by a high oxidation resistance and still has a mechanical strength at temperatures of over 1000.degree. C. which favors its use as structural material in gas turbines.
