Title: Innovations by Inventor Alex Cho
Introduction
Alex Cho is a notable inventor based in Richmond, VA (US), recognized for his contributions to the field of aluminum-lithium alloys. With a total of 12 patents to his name, Cho has made significant advancements in material science, particularly in enhancing the properties of aluminum-lithium alloys for commercial applications.
Latest Patents
One of Cho's latest patents focuses on a method of minimizing strength anisotropy in aluminum-lithium alloy wrought products. This innovative approach involves subjecting these alloys to an improved T8 temper practice. The process begins with solution heat treating and quenching, followed by a combination of cold rolling and stretching steps prior to aging. The cold rolling can range between 1 and 20% reduction, while the stretching step can vary between 0.5-10%. Notably, the cold rolling may be performed in one or multiple passes, with the possibility of rolling in different directions to further enhance reductions in strength anisotropy. The result is an aluminum-lithium alloy wrought product that exhibits increased minimum tensile yield stress throughout its thickness and in various directions, making it suitable for high-strength applications.
