Title: Innovations of James Terry Lewis
Introduction
James Terry Lewis is an accomplished inventor based in Cuyahoga Falls, OH (US). He holds a total of 2 patents that showcase his expertise in the field of materials engineering, particularly in the development of high-strength steel wire.
Latest Patents
One of his notable patents is for high strength, high carbon steel wire. This invention aims to achieve a drawn wire with a tensile strength defined by the equation of Y=Yexp(Aε), where Y represents the tensile strength in MPa (N/mm). The wire contains 0.95 to 1.3% carbon and a combination of chromium, manganese, silicon, cobalt, niobium, and boron. The processing method ensures that the bright wire has a structure void of micro cracks, producing a desired microstructure with defined inter-lamella spacing and austenite grain. The wire is coated with brass and fine drawn with an optimized die draft schedule at a specified true strain.
Another significant patent by Lewis involves the drawing of steel wire. This process entails drawing steel wire from an initial diameter to a desired final or intermediate diameter using a non-linear tapered draft. The wire is drawn through a series of successive dies, gradually reducing the diameter while adjusting the drawing strain based on the actual strength of the steel at each die. Additionally, the wire may undergo a skin pass, reducing the diameter by less than 4% after reaching the final or intermediate diameter.
