Surface structure and catalytic activity of amorphous metallic alloys Fe-Nb-B-RE (RE = Y, Gd, Tb, Dy) in alkaline solution

Surface structure and catalytic activity of amorphous metallic alloys Fe-Nb-B-RE (RE = Y, Gd, Tb, Dy) in alkaline solution

The thermal stability and characteristics of the surface of the Fe 82 Nb 2 B 14 RE 2 (RE = Y, Gd, Tb, Dy) amorphous alloys were studied by differential scanning calorimetry and atomic force microscopy methods. Alloying of the Fe 84 Nb 2 B 14 alloy by 2 at.% of RE results to increase of nanocrystalli...
