Title: The Innovative Contributions of Allen J. Paxson

Introduction

Allen J. Paxson is a distinguished inventor based in Cincinnati, OH, whose contributions to the field of nickel-base superalloys have significantly advanced material science. With a total of four patents to his name, Paxson's innovations focus on enhancing the properties of nickel-base superalloys, particularly their resistance to abnormal grain growth.

Latest Patents

One of Paxson's latest patents describes a nickel-base superalloy that exhibits improved resistance to abnormal grain growth. This groundbreaking alloy is designed to minimize nucleation tendencies and control grain growth, featuring a fine dispersion of a second phase. This second phase plays a critical role in preventing random grain growth during heat treatment, yielding a uniform microstructure with a grain size range of approximately 2 to 3 ASTM units. The superalloy contains a minimum of about 0.030 weight percent carbon or 27 to 2000 ppm yttrium, promoting a suitable volume fraction of the second phase to cover at least 10 percent of the grain boundary area.

Another patent by Paxson outlines a method for forming nickel-base superalloys with improved resistance to abnormal grain growth. This method involves alloying the nickel-base superalloy with a calculated minimum amount of carbon. When processed correctly, this carbide phase successfully restricts grain boundary motion during supersolvus heat treatment, ensuring uniform grain size and preventing undesirable random grain growth.
