Title: Ikurou Hashimoto: Innovator in Hot-Dip Galvanized Steel Sheets
Introduction
Ikurou Hashimoto is a notable inventor based in Kobe, Japan. He has made significant contributions to the field of materials science, particularly in the development of hot-dip galvanized steel sheets. With a total of 2 patents, his work has had a considerable impact on the industry.
Latest Patents
Hashimoto's latest patents focus on enhancing the properties of hot-dip galvanized steel sheets. The first patent describes a hot-dip galvanized steel sheet that excels in adhesion with a hot-dip galvanized zinc layer. This invention ensures high tensile strength and good formability, even when using a steel sheet containing relatively larger amounts of silicon (Si) and manganese (Mn). The composition includes a basis steel sheet with Si ranging from 0.05 to 2.5% and Mn from 0.2 to 3%, by mass. The design features a Fe plated layer and a hot-dip galvanized zinc layer, with oxides containing Si and/or Mn dispersed near the interface.
The second patent also pertains to a hot-dip galvanized steel sheet, emphasizing the formation of an Si-Mn enriched phase at the interface. This phase is observed under electron microscopes and contains more than twice the amount of Si and/or Mn compared to the basis steel sheet. This innovation ensures that the hot-dip galvanized steel sheet remains free of bare spots, even when the basis steel sheet contains higher amounts of Si and Mn.
