Title: Innovations of Geoffrey K Sigworth
Introduction
Geoffrey K Sigworth is a notable inventor based in Reading, PA (US). He has made significant contributions to the field of aluminum casting alloys, holding a total of 11 patents. His work focuses on improving the properties of aluminum alloys, particularly in terms of hot crack resistance.
Latest Patents
One of his latest patents is a method for grain refinement of high strength aluminum casting alloys. This method involves casting an aluminum base alloy to produce a cast product with enhanced hot crack resistance in the as-cast condition. The process includes providing a melt of an aluminum base alloy with specific compositions, including 2.0 to less than 3.5 wt. % Zn and 2.5 to less than 4 wt. % Mg, among other elements. A nucleating agent, selected from metal carbides, aluminides, and borides, is added to the melt to facilitate grain refining. The resulting alloy is solidified to achieve a grain size of less than 125 microns, ensuring it is free of hot cracks.
Another patent by Sigworth also focuses on a method for grain refinement of high strength aluminum casting alloys. This method specifies a melt composition that includes 4 to less than 5 wt. % Cu and maintains dissolved Ti in the range of about 0.005 to 0.05 wt. %. Similar to his other patent, a nucleating agent is incorporated to improve the alloy's resistance to hot cracking, resulting in a cast product with a grain size of less than 125 microns.
