Abstract:

Conservation of critical metals or their raw materials is generally sought in a number of ways by substitution, i.e., either by lowering the critical alloy content in existing materials leaning or by developing alternative materials from cheaper raw materials which are readily available on a long-term basis by the application of critical materials only where they are needed by the application of near-net-shape manufacturing processes by taking measures designed to extend the life of components and by remelting scrap metal, accompanied by minimum possible downgrading. The present paper discusses specific measures for reducing waste and for extending life as applied to engine components. Some of the methods and techniques used toward this end were evolved with other purposes in mind e.g., light-weight construction. It is nevertheless shown that appreciable savings in materials or gains in life can be achieved for engine parts and that the concepts employed can also readily be transferred to other areas.
