| description | 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 nanocrystallization temperature on 110 K for amorphous Fe 82 Nb 2 B 14 RE 2 (RE = Y, Gd, Tb, Dy). Values of the roughness increased after thermal treatment for 1 h in air due to nucleation and growth of nanocrystals in bulk and surface oxidation of the amorphous Fe82Nb2B14RE2 alloys. The nanocrystallization of Fe 82 Nb 2 B 14 RE 2 amorphous alloys after thermal treatment increases the catalytic activity for hydrogen evolution reaction. |
