摘要: Abstract Fe 91– x Mo 8 Cu 1 B ( = 12, 15, 17, 20) amorphous and nanocrystalline alloys were studied to examine the influence of content on their microstructure magnetic behaviour. Changes in properties provoked by microstructural evolution upon thermal treatments as-cast samples also analyzed. Nanocrystallization kinetics can be described an isokinetic approach except for 20 at.% alloy. The Curie temperature increases with alloy’s content. Mossbauer results suggest presence atoms nanocrystals. Crystalline volume fraction mean grain size nanocrystals at end nanocrystallization process are higher lowest alloy develops a boride phase just after early stages process, which provokes hardening this softest behaviour compositions corresponds nanocrystallized 17 at.%
