Latest Patents

Satoru Yusa holds a patent for "High toughness steel and a method for manufacturing the same." This patent describes a process where ups and downs with a cycle of not more than 5 µm and an amplitude of not less than 200 nm are formed in a part of not less than 70% per unit length of a prior-austenite grain boundary. This is observed in a linear form when viewed from a vertical plane. The method involves subjecting steel in a state of austenite to a deformation of not less than 30% of a total area reduction rate at a temperature lower than the recrystallization temperature of austenite. Subsequently, the deformed steel is cooled without causing recrystallization or phase transformation of a diffusion type. He has 1 patent to his name.
