Introduction

Yoshio Kono is a notable inventor based in Aichi, Japan. He has made significant contributions to the field of metallurgy, particularly in the heat treatment of steel. His innovative methods have enhanced the strength and durability of steel products.

Latest Patents

Kono holds a patent for a method for heat treatment of steel. This method involves carburization hardening, which forms carburized steel, followed by a second hardening process. The technique reduces the grain size of steel while precipitating carbonitrides inside the grains, thereby increasing the strength of the heat-treated steel. The process includes heating the steel to a first austenitic temperature range in a carburizing gas atmosphere, cooling it to a martensitic temperature range, and quenching the steel. The second hardening involves heating the carburized steel to a second austenitic temperature range in a similar atmosphere and quenching it again.
