富Ｆｅ的Ｎｄ－Ｆｅ－Ｂ纳米晶合金的磁性和结构实验用的含８８～９０ａｔ％Ｆｅ的Ｎｄ－Ｆｅ－Ｂ合金在电弧炉中熔炼，用单辊快淬设备制成１５μｍ厚、１ｍｍ宽的条带，冷却辊速约为４２ｍ／ｓ。条带在８～１０－３Ｐａ真空下于８７３～１０２３Ｋ退火６０～３６００ｓ，...
Magnetic and structural experiments of the Fe-rich Nd-Fe-B nanocrystalline alloy The Nd-Fe-B alloy containing 88-90 at% Fe was melted in an electric arc furnace and was formed into a 15 μm thick, 1 mm wide Of the strip, cooling roller speed of about 42m / s. Strips annealed at 873 ~ 1023K for 60 ~ 3600s under vacuum of 8 ~ 10-3Pa, ...
