Abstract

Uma composição de liga Fe(100-x-z)BxPyCuz, onde os índices X, Y, Z respectivamente satisfazem as seguintes condições: 4 = X = 14% atômico; 0 = Y = 10% atômico; e 0,5 = Z = 2% atômico. Esta composição de liga tem uma fase amorfa como fase principal e é usada como material de início e é submetida a tratamento térmico, de modo que nanocristais compreendendo não mais que 25 nm de bccFe sejam cristalizados. Assim, obtendo uma liga nanocristalina baseada em Fe com melhores propriedades magnéticas.
