Shock Thermomechanical Processing of Superalloys

  • H. E. Otto


Nickel-base superalloys have become the primary material used in gas turbine engines for blades, brackets, disks, and other components. Most of the effort on nickel base materials has been to extend their high-temperature capabilities to increase the efficiency of the engine. As such, the mechanical properties of high-temperature alloys are influenced by variations in the metallurgical history of the materials. Varying heat treatments, casting techniques, powder metallurgy production and consolidation processes, and mechanical working and machining are all factors that influence the resulting mechanical properties. As a result, a continuing effort is being made to relate the factors involved from the initial chemistry through the processing steps to the final product to produce a product with improved high-temperature properties for gas turbine engines. At times there are conflicts between the various processes that result in a compromise situation.
