Abstract
Official abstract text for this publication.
An amorphous alloy particle is an amorphous alloy particle formed of an iron-based alloy, and the particle contains a grain boundary layer.
First claim
Opening claim text (preview).
What is claimed is: 1. An amorphous alloy particle formed of an iron-based alloy, the particle comprising a plurality of primary particles plastically deformed into the amorphous alloy particle, each primary particle having a grain boundary layer surrounding the respective primary particle. 2. The amorphous alloy particle according to claim 1 , wherein each grain boundary layer has a thickness of 200 nm or less. 3. The amorphous alloy particle according to claim 1 , wherein the iron-based alloy contains Fe, Si, and B. 4. The amorphous alloy particle according to claim 2 , wherein the iron-based alloy contains Fe, Si, and B. 5. The amorphous alloy particle according to claim 1 , wherein each grain boundary layer is a layer formed of elemental oxygen and an oxide of a metal element contained in the primary particle. 6. The amorphous alloy particle according to claim 1 , wherein the amorphous alloy particle has an intragranular electrical resistivity greater than 100 μΩ·m.
