【摘要】 本文对Fe₇₃Nb_xAl_5-xGe₂P₁₀C₆B₄（x=1、3、5at%）非晶合金的过冷度及磁性进行了研究。结果表明:该合金系具有较宽的过冷液相区和较强的玻璃形成能力,△T_x 分别为66K,62K 和45K.Nb 为1at%时合金具有最大过冷度（66K）,采用1000r/min 辊速喷制的合金条带为完全非晶相且厚度为100μm,饱和比磁化强度σ_s=148Am²/kg,矫顽力H_c=52A/m。经500℃退火15min 后,试样的σ_s=149 Am²/kg,矫顽力明显下降H_c=31.2A/m。更多还原

【Abstract】 Supercooled liquid region and magnetic properties of Fe₇₅Nb_xAl_5-xGe₂P₁₀C₆B₄（x=1、3、5 at%） amorphousalloys have been studied. The results show that there are broader suppercooled liquid regions ΔT_x and larger ability toform glass for the alloys, the ΔT_x is 66K,62K and 45K respectively.When the Nb content is 1%,there is the biggestΔT_x（66K） for the alloy, and amorphous ribbon with 100μm thick was prepared by single-roller melt spinning method（1000r/min）. The saturation magnetization σ₈ and coercivity H_c is 148Am²/Kg and 52A/m respectively forFe₇₅Nb₁Al₄Ge₂P₁₀C₆B₄ amorphous alloy at as-quenched, they are 149 Am²/Kg and 31.2A/m for the sample annealed at500℃ for 15 minutes.更多还原
