Abstract
Abstract The effects of Si addition on the nano-eutectic structure and soft magnetic properties of bulk Fe 83 B 17− x Si x ( x =0–5 at%) alloy rods were investigated. The addition of Si increases the volume fraction of the α-Fe dendrite phase and decreases the average lamellar spacing of the eutectic structure to less than 100 nm. As a result, the intrinsic coercivity ( H c) is decreased effectively, while the saturation magnetization ( M s) remains stable. The annealing experiments of the Fe 83 B 13 Si 4 alloy show further that addition of a less than 4 at% Si content can improve the thermal stability of the nano-lamellar eutectic structure and the soft magnetic properties.
