“…In other words, the solidification temperature range ∆T l (T l -T m ) of ribbons does not change monotonically. The results show that Cr21 ribbon is the closest component to the eutectic point [30]. Table 1.…”

“…This indicated that the FeSiBNb alloy with a small amount of Cr could form amorphous ribbons. As the Cr content increased, the position of the diffuse emission peak decreased from 44.6 • to 43.2 • , indicating an increase in the average atomic spacing, and the free volume within the ribbons also increased [30]. At the same time, the ribbons became increasingly brittle, and the XRD of the Cr36 ribbon showed evident crystal peaks.…”

The effect of the Cr element on the corrosion behavior of as-spun Fe72−xCrxB19.2Si4.8Nb4 ribbons with x = 0, 7.2, 21.6, and 36 in 3.5% NaCl solution were investigated in this work. The results show that the glass formability of the alloys can be increased as Cr content (cCr) is added up to 21.6 at.%. When cCr reaches 36 at.%, some nanocrystals appear in the as-spun ribbon. With increasing cCr content, the corrosion resistances of as-spun Fe-based ribbons are continually improved as well as their hardness properties; during the polarization test, their passive film shows an increase first and then a decrease, with the highest pitting potential as cCr = 7.2 at.%, which is confirmed by an XPS test. The dense passivation film, composed of Cr2O3 and [CrOx(OH)3−2x, nH2O], can reduce the number of corrosion pits on the sample surface due to chloride corrosion and possibly be deteriorated by the overdosed CrFeB phase. This work can help us to design and prepare the highly corrosion-resistant Fe-based alloys.

The Fe80PxC20-x 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 (cP) can inhibit the precipitation of primary α-Fe and graphite phases, and promote the formation of eutectic α-Fe + Fe3C + Fe3P phases in ingots and annealed ribbons. With increasing annealing temperature (Tan), the primary α-Fe grain size of the ribbons with cP = 4.5 at.% increases gradually and that of the ribbons with cP = 6.5 at.% increases firstly and then decreases. The degradation performance and reusability of the ribbons show a similar Tan-dependent behavior, which can be explained by the size effect of the galvanic cells. Meanwhile, the saturation magnetisation Bs and coercivity Hc of the ribbons with cP = 4.5 and 6.5 at.% increase with increasing Tan, showing a near-linear change of the reaction rate constant k against ln (Bs·Hc). 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.
