Nd-Fe-B-Si合金的研究

STUDY ON THE Nd-Fe-B-Si ALLOYS
Abstract:
Si-doped Nd-Fe-B-alloys (Nd15Fe77-xSixB8, x=4,8, 16, 18 at%) were prepared in a graphite furnace. X-ray diffraction and scanning electron micrographs of the products showed that besides Nd2Fe14B there were some Nd-rich phases when silicon had doped in at 8 at%.The Curie temperature(TC) was increased from 310℃ to 350℃ by do ping with 8-16 at% silicon. When Si content was greater than 16 at%, a new phase was formed and the TC of the alloy markedly decreased. The density of the alloy slightly deereases with increase of Si when Si content is over 4 at%. The hardness of the alloy has a maximum value at about 8 at% of Si.
