This report delineates the factors influencing the characteristics, design, and properties of high-performance castings and the outstanding problems that must be resolved to increase their reliability and use. Programs and methods for improving the integrity and acceptance of such castings are suggested. A satisfactory end-product requires close cooperation between the product designer and the foundryman; therefore, to use high-performance castings at their full potential, reliable design data must be available to the designer, and designers must become as knowledgeable about casting design procedures as they are about the design of forgings and other products. In addition, reliable, nondestructive evaluation tests are necessary in the development of casting processes and in the final inspection of the castings. Nondestructive evaluation also should be involved in the specifications in phases such as design, development, processing, and inspection. Finally, contracts should be awarded only to qualified foundries and not primarily on a price basis. An integrated plan is proposed to make castings produced in this way competitive with forgings, and specific recommendations are proposed for individual metallic-alloy systems.
