The influence of an ordering transition on the interdiffusion in Fe-Si alloys

Assessment of Si and Al diffusion for the production of high Si and high Si–Al electrical steel

“…It does not agree completely with the D(c) values reported by Rabkin et al [5]. However, the experiments carried out in this work involve ternary Fe-Si-Al diffusion, whereas Rabkin worked with binary Fe-Si diffusion.…”

Microstructure and mechanical properties of rapidly quenched Fe–6.5wt.% Si alloy

“…As to its high Si content, Fe-6.5 wt.% Si alloy is very brittle at room temperature due to appearances of ordered phases like B2 and D0 3 [2,3]. The ductility of as cast Fe-6.5 wt.% Si alloy at room temperature is almost zero, thus hindering the production of this alloy by hot and cold rolling method [4].…”

Study on the Si penetration into Fe sheets using PVD method and its application in the fabrication of Fe-6.5wt.% Si alloys

“…With more Si entering the Fe substrate, γ-Fe(Si) phase starts to transform to α-Fe(Si) phase. Knowing that Si atoms diffuse more quickly in α-Fe(Si) phase than in γ-Fe(Si) [20,21], Si penetration can be suggested to be controlled by its migration through the α-Fe(Si) and γ-Fe(Si) interface. The argument is confirmed by the result that a critical point at which the Si concentration dropped quickly appears around 1.9 wt.%, as shown in Fig.…”
