Si microalloying optimizes the thermal stability, crystallization behaviors and magnetic properties of Fe-rich Fe-B-Cu-Hf alloys

A Review of Fe‐Based Amorphous and Nanocrystalline Alloys: Preparations, Applications, and Effects of Alloying Elements

“…When x = 2 at%, the nanocrystalline alloy Fe 82.65 Cu 1.35 Si 2 B 14 has the best soft magnetic properties, with the H c value of 6.5 A m −1 and the B s value of 1.84 T. In 2020, Yuan studied the effect of microsubstitution of Si for B on amorphous forming ability of Fe 86 B 13− x Si x Cu 0.4 Hf 0.6 alloys. [ 53 ] The results showed that the effect of Si microalloying was significant. When the Si content was smaller than 1 at%, with the increase of Si content, the apparent activation energy of α‐Fe crystallization decreased, while the apparent activation energy of Fe–B crystallization increased.…”

Fe‐Based Amorphous Alloy Coatings: A Review

“…The general application of different alloying elements such as Si can be found in numerous research works. [ 26–75 ] It has been indicated that Si affects the ability to form amorphous more than P element, [ 76 ] Li et al [ 76 ] reported an increase in the Si/P ratio raises the amorphous formation ability(AFA). AddingSior P decreases the first crystallization onset temperature, while a reduction in the Si/P ratio leads to higher thermal stability in the second crystallization.…”
