Abstract
- The Fe<subscript>80</subscript>P<subscript>x</subscript>C<subscript>20-x</subscript> ingots and amorphous ribbons (4.5 ≤ x ≤ 6.5) are arc melted and melt spun respectively. The Rhodamine B degradation performance of as spun and annealed ribbons are investigated with various methods. In present alloys, increasing P content (c<subscript>P</subscript>) can inhibit the precipitation of primary α-Fe and graphite phases, and promote the formation of eutectic α-Fe + Fe<subscript>3</subscript>C + Fe<subscript>3</subscript>P phases in ingots and annealed ribbons. With increasing annealing temperature (T<subscript>an</subscript>), the primary α-Fe grain size of the ribbons with c<subscript>P</subscript> = 4.5 at.% increases gradually and that of the ribbons with c<subscript>P</subscript> = 6.5 at.% increases firstly and then decreases. The degradation performance and reusability of the ribbons show a similar T<subscript>an</subscript>-dependent behavior, which can be explained by the size effect of the galvanic cells. Meanwhile, the saturation magnetisation B<subscript>s</subscript> and coercivity H<subscript>c</subscript> of the ribbons with c<subscript>P</subscript> = 4.5 and 6.5 at.% increase with increasing T<subscript>an</subscript>, showing a near-linear change of the reaction rate constant k against ln (B<subscript>s</subscript>·H<subscript>c</subscript>). This work not only studies the mechanism of improving degradation performance for FePC amorphous alloys by annealing treatment, but also reveals a correlation between degradation performance and magnetization performance of FePC alloys.
