Abstract
The invention relates to an alloy having high temperature mechanical strength in an oxidizing medium and comprising a carbide-precipitation-strengthened matrix containing chromium. The invention is characterized in that the alloy comprises carbides of at least one metal (M) selected from among titanium, zirconium and hafnium, said carbides also optionally containing (M′) tantalum. The invention is suitable for articles that require high temperature mechanical strength, such as for hot glass processing or production.
