Effect of Si on the Glass Formation and Magnetic Properties of High-Iron Fe–Zr–Si Alloys

High-iron Fe–Zr–Si amorphous ribbons were fabricated through the melt-spun technique. Then, the effects of Si content on the glass-forming ability and magnetic properties of Fe 90− x Zr 10 Si x ( x = 1, 2, 3, 4, 5, 10) alloys were investigated. Results showed that the amorphous structure only formed...

Description
Summary:High-iron Fe–Zr–Si amorphous ribbons were fabricated through the melt-spun technique. Then, the effects of Si content on the glass-forming ability and magnetic properties of Fe 90− x Zr 10 Si x ( x = 1, 2, 3, 4, 5, 10) alloys were investigated. Results showed that the amorphous structure only formed in an alloy composition of 3 at.% Si. Moreover, α -Fe(Si) and Fe 3 Zr phase appeared gradually when Si was added. Fe 87 Zr 10 Si 3 alloy is a unique amorphous structure in Fe 90− x Zr 10 Si x ribbons. The peak temperatures of the two crystallization stages were 464 and 600 ∘ C. The saturation magnetization ( M s ) values of the alloys ranged from 91.2 to 132.3 emu/g, and all had an initial increase before decreasing and their coercivity ( H c ) values increased with increased Si content. The Fe 87 Zr 10 Si 3 amorphous alloy exhibited a low H c value of approximately 39.1 A/m, which shows good magnetic properties in the as-quenched state. After annealing, the M s of the amorphous sample considerably improved, particularly reaching 165.3 emu/g at 600 ∘ C.
