Zusammenfassung: | In a method of making an alloy in which superior cyclic properties may be achieved by avoiding the presence of oxide inclusions and of Titanium Carbo-Nitride stringers, the alloy constituents are first melted in a way which avoids contact with the refractory material from which the oxide inclusions normally derive, for example, by electron-beam melting in a water-cooled copper crucible in a vacuum or protective atmosphere. The thus formed alloy is then powdered, again in a refractoriless process, by melting the end of a spinning ingot, so that the physical separation of the powder particles prevents agglomeration of the stringers. The clean powder is finally consolidated. |
