AbstractThis approach has required work in the three broad areas of process development, material development, and quality assurance. The first has led to the development of an automated casting facility, and the adoption of the technically more difficult seeding technique, as a result of its greater process and design flexibility. The second has been met by the development of a series of three alloys to meet specific turbine applications and the economies necessary to make the complex shapes to the required precision. The third has been met by the development of SCORPIO, a real-time rapid-orientation measurement system for the production environment, and the understanding and development of the process controls necessary to control wall section measurements and heat treatment. By the involvement of multidisciplined teams, this approach has led to a demonstrated technology with little or no cost penalty.MST/244
