Title: Innovations of David D McDevitt
Introduction
David D McDevitt is a notable inventor based in Greenwood, IN (US). He has made significant contributions to the field of materials science, particularly in the development of advanced brass alloys. With a total of 4 patents to his name, McDevitt's work focuses on enhancing the properties of brass to improve its machinability and corrosion resistance.
Latest Patents
One of McDevitt's latest patents is for a corrosion-resistant bismuth brass. This innovative alloy contains bismuth and phosphorous, which, when maintained within a critical range, allows the material to exhibit good elevated temperature tensile elongation between 100°C and 350°C. This property is achieved without compromising machinability due to phosphide formation. Additionally, the alloy includes a tin addition that enhances its corrosion resistance, providing a superior performance compared to either element alone.
Another significant patent involves machinable copper alloys with reduced lead content. This invention claims a machinable alpha-beta brass that incorporates bismuth to improve machinability. In this alloy, either a portion of the zinc is replaced with aluminum, silicon, or tin, or a portion of the copper is substituted with iron, nickel, or manganese. These modifications aim to create safer and more efficient materials for various applications.
