AbstractForging technology has been developed to the point where wrought nickel alloy turbine blades can be manufactured to accurate dimensional tolerances and consistent metallurgical characteristics. Metallurgists and engineers have utilized theoretical knowledge and practical understanding of nickel superalloys and the forging process to meet the ever-increasing temperature and stress demands of turbine engines. New materials, forging techniques, and the use of computer-aided design and manufacturing systems are being developed to compete with advanced casting technology.MST/259
