The Influence of Heat Treatment on the Structure and Properties of an Isothermally Forged Ti-6Al-6V-2Sn Nose Wheel and Structural Shape.

摘要

Two isothermal forgings, an F111 nose wheel and a structural shape were sectioned, heat treated and evaluated by metallography and by tensile and fracture toughness tests. Results indicate reasonable uniformity of structure and properties throughout the isothermal forgings, and heat treatment response similar to that of conventional forgings of the same alloy. The as-forged microstructure is largely dependent on the preform microstructure. (Author)
