Latest Patents

Chih-Pu Chang holds a patent for a "Method for manufacturing high-strength and high-ductility steel." This method involves several steps, starting with the provision of alloy steel. The alloy steel is then hot rolled, resulting in a microstructure that includes austenite, bainite, and martensite. Following this, the hot-rolled alloy steel undergoes annealing to decompose the bainite and martensite structures into ferrite and austenite. The process continues with cold rolling and a second annealing step, ultimately producing a high-strength and high-ductility steel with 50% to 70% residual austenite.
