Title in Portuguese
Evolução microestrutural e propriedades magnéticas de ligas fesi e FeSi sinterizadas com auxílio de fluxante.

Abstract in Portuguese
Nesta dissertação apresentam-se resultados relativos a evolução microestrutural de amostras sinterizadas a partir de misturas de pó de ferro ou ferro-fósforo com pó atomizado de liga ferro-30% silicio. A temperatura de sinterização foi o principal parâmetro, variando de 880 a 1180'GRAUS'c. A utilização de 'NA IND.2''CO IND.3' como fluxante foi efetiva no sentido de remover a camada óxida presente na superficie das partículas de'FE''SI' promovendo interdifusão já a partir de 880'GRAUS'c. Amostras sinterizadas a 1180'GRAUS'c apresentam microestrutura homogênea. Resultados de propriedades magnéticas são apresentados. O comportamento magnético em função de frequência de ensaioé o principal aspecto investigado.

Abstract in English
The effect of sintering temperature on microstructure of fluxed FeSi and FeSiP sintered alloys produced with pre-mixed powders is the aim of this work. A pre-mix of Fe or PeP with water atomized Fe3OSi powsers was used. The utilization of 'NA IND.2''CO IND.3' to flux the superficial oxides on FeSi particles was eficiente to promote interdiffusion already tt 880 °C. Fluxed samples sintered at 1180 °C are homogeneous. Magnetic and electrical properties are presented. The magnetic behaviour versus frequency is the more importante aspect investigated.
