通過(guò)成分調(diào)整獲得高飽和磁感應(yīng)強(qiáng)度的鐵基非晶合金帶材,用差式掃描量熱儀(DSC)分析其非晶形成能力和晶化行為,根據(jù)確定的兩級(jí)起始晶化溫度,選擇合適的熱處理工藝,并對(duì)退火后的非晶合金帶材進(jìn)行磁致伸縮性能測(cè)試。結(jié)果表明:適當(dāng)提高Fe元素的含量、合理控制C和Si的比例,可得到飽和磁感應(yīng)強(qiáng)度高、矩形度好、磁致伸縮低、噪音小的非晶合金帶材,其飽和磁感應(yīng)強(qiáng)度Bs>1.65 T,矯頑力<3 A/m,磁致伸縮振幅λp-p為836 nm/m,加權(quán)噪聲值為59 dB,矯頑力與λp-p成正相關(guān)關(guān)系,軟磁性能更好。高飽和磁感應(yīng)強(qiáng)度非晶合金的磁化曲線(xiàn)矩形比高,從而使得磁疇壁移動(dòng)區(qū)域更大,噪聲更低。
- Abstract:
-
The Fe-based amorphous alloy strip with high saturation magnetic induction was obtained through appropriate composition adjustment. The amorphous forming ability and crystallization behavior were analyzed by DSC, and the appropriate heat treatment process was selected according to the determined initial crystallization temperature of two stages, at the same time, the magnetostrictive properties of the annealed amorphous alloy strips were tested. The results show that the amorphous alloy with high saturation magnetic induction, good rectangular degree, low magnetostriction and low noise can be obtained by properly increasing the content of iron and reasonably controlling the content ratio of C and Si, its saturation magnetic induction Bs is higher than 1.65 T, coercivity is less than 3 A/m, magnetostrictive amplitude is 836 nm/m, weighted noise value is 59 dB. The coercivity is positively correlated with magnetostrictive amplitude, soft magnetic performance is better. Because of the higher rectangular ratio of magnetization curve of high saturation magnetic induction amorphous alloy, the domain wall moving region is larger and the noise is lower.
