|1. (WO2015137303) MAGNETIC CORE, COIL COMPONENT AND MAGNETIC CORE MANUFACTURING METHOD|
|Applicants:||HITACHI METALS, LTD.
|Title:||MAGNETIC CORE, COIL COMPONENT AND MAGNETIC CORE MANUFACTURING METHOD|
This magnetic core has a structure in which alloy phases (20), which include Fe, Al, Cr and Si, are dispersed. Adjacent alloy phases (20) are connected by grain barrier phases (30), and in the grain barrier phases (30), oxide regions are generated which include Fe, Al, Cr and Si and which include a higher mass ratio of Al than the alloy phases (20). Defining the total of Fe, Al, Cr and Si as 100 mass%, this magnetic core contains 3-10 mass% Al, 3-10 mass% Cr, and more than 1 mass% and less than or equal to 4 mass% Si, with the remainder being Fe and unavoidable impurities.
