    Abstract

    Hot rolled rings made from nickel-based superalloys are used for the manufacture of rotating components in jet engines and land-based turbines. Contoured rings are attractive to manufacturers because they can simplify and improve manufacturing operations by reducing machining times and, in some cases, eliminating welding operations. ATI 718Plus is a nickel-based superalloy designed to achieve high strength and thermal stability at elevated temperatures while exhibiting good formability during forging operations, characteristics that making it a suitable alloy for the manufacture of contoured rings. This work presents the results of a series of solution and precipitation heat treatments of rings made from ATI 718Plus with the goal of optimizing their processing and mechanical behavior. Microstructural characteristics and mechanical properties are reported, including the results of tensile tests conducted at room temperature and at high temperature and of hardness and stress-rupture testing. The results of this work were implemented at a local factory to ensure the required mechanical properties of heat-treated parts.
