Title: Roy L Athey: Innovator in Superalloy Forging and Turbine Disk Production
Introduction
Roy L Athey is a notable inventor based in North Palm Beach, FL (US). He has made significant contributions to the field of materials engineering, particularly in the development of advanced forging processes for superalloys and turbine disks. With a total of 3 patents to his name, Athey's work has had a profound impact on the aerospace and manufacturing industries.
Latest Patents
Among his latest patents is the "Superalloy Forging Process," which outlines a method for producing fine grain forged superalloy articles with high yield strength at intermediate temperatures. The preferred starting composition includes 15% Cr, 13.6% Co, 4.1% Mo, 4.6% Ti, 2.2% Al, 0.01% C, 0.007% B, 0.07% Zr, with the balance being Ni. This innovative material is forged at temperatures above the gamma prime solvus and at a true strain of at least 0.5. Alternatively, it can be forged below the gamma prime solvus temperature with intermediate super solvus anneals, resulting in a fine grain material that can be heat treated or further isothermally forged to create complex shapes.
Another significant patent is the "Method of Producing Turbine Disks," which describes a technique for creating metallic articles, particularly turbine disks, that possess varying properties in different regions. This method involves an initial hot-working step, followed by an intermediate heat treatment, and concludes with a final warm-working step, allowing for tailored mechanical properties.
