The present state of foundry technology pertinent to the production of high performance HY-130 and HY-180 steel and titanium alloy castings is assessed. Problems encountered in current production and those anticipated in future production of large castings up to 20,000 pounds finished weight are discussed. Programs and approaches to resolve these problems are recommended. Factors considered were specific melting processes and furnaces for preparing and refining molten alloys, casting design, mold and pouring practice, influence of chemical composition, impurity elements, heat treatment and other processing variables on mechanical properties of casting, present and anticipated foundry problems with specific alloys, weld repair and structural joining, scrap reclamation, and appropriate procurement specification requirements to assure attainment of desired properties and qualities in castings of all sizes.
