Title: The Innovative Contributions of Carmen C. Manzonelli
Introduction
Carmen C. Manzonelli is a notable inventor based in Weirton, West Virginia. She has made significant contributions to the field of materials science, particularly in the development of aluminum-magnesium alloys. With a total of three patents to her name, her work has had a considerable impact on the manufacturing processes of aluminum products.
Latest Patents
Carmen's latest patents include a method of producing high tensile aluminum-magnesium alloy sheet. This innovative process involves creating a sheet from an aluminum-based melt containing a relatively low percentage of magnesium, specifically between 1.5-2.3%. The melt is formed into a sheet with a uniform thickness ranging from 1/8 to 1/2 inch and is quenched to a temperature below about 500°F within three minutes. The resulting aluminum-magnesium alloy sheet achieves a fully-hardened tensile strength exceeding 50,000 psi. Another significant patent is for a method of casting aluminum base alloy sheet and product. This method addresses the issue of edge cracking in continuous casting of aluminum base alloy in sheet form. By adjusting the composition of the alloy, Carmen has found a way to eliminate or significantly reduce edge cracking, thereby minimizing waste and production costs.
