Latest Patents

One of his latest patents is for batch-annealed dual-phase steel. This dual-phase steel consists essentially of a ferrite matrix containing islands of martensite. It is produced by batch annealing of hot or cold rolled steel having carbon below 0.2% and manganese below 2%, with critical contents of copper (0.4%) and nickel (0.6%). The process involves heating to the alpha plus gamma region, followed by slow cooling. This method is effective and controllable, yielding a dual-phase steel product that exhibits high tensile strength and excellent elongation properties, along with good yield strength upon moderate deformation.

Another significant patent is for high strength, low alloy steel. This steel is produced, preferably as a hot rolled article, to have a rimmed skin of essentially ferrite while having a main body or core that is aluminum-killed. It comprises a suitable quantity of columbium and/or vanadium for superior mechanical properties, including yield strength. The carbon, manganese, and sulfur contents of the base metal are limited to provide special results as low alloy steel, avoiding unwanted directionality regarding toughness and bendability. The steel is made by pouring a mold 80-95% full of the base composition, allowing the steel to rim for several minutes, and then continuing to pour while adding aluminum and columbium or vanadium to the teemed stream.
