Title: Isamu Yoshii: Innovator in Magnetic Alloys
Introduction
Isamu Yoshii is a notable inventor based in Sendai, Japan. He has made significant contributions to the field of magnetic alloys, holding a total of 2 patents. His work focuses on enhancing the magnetic characteristics and workability of these materials.
Latest Patents
Yoshii's latest patents include innovative formulations of magnetic alloys. The first patent describes a magnetic alloy that contains not less than 0.03 weight percent but not more than 5.0 weight percent of phosphorus (P), along with specified amounts of titanium (Ti), niobium (Nb), and zirconium (Zr). This alloy also includes 2.5 to 10 weight percent silicon (Si), with the remainder primarily consisting of iron (Fe). The unique feature of this alloy is the segregation of P on the grain boundaries, which results in superior magnetic characteristics and workability, allowing the alloy to be rolled.
The second patent outlines another magnetic alloy that contains not less than 0.03 weight percent but not more than 5.0 weight percent of P, and a total of 3.0 to 26.0 weight percent of aluminum (Al) and silicon (Si). In this formulation, Al is present in amounts ranging from 0.01 to 13.0 weight percent, and Si is also present in similar proportions. The remaining part of the alloy consists mainly of Fe, and it is characterized by the presence of P on the grain boundary in amounts exceeding 0.5 weight percent of the atoms forming that boundary.
