【摘要】 研究了Fe₈₃Ga₁₇Er_0.4轧态合金不同热处理方式下的磁致伸缩性能及显微组织,并对比了不同热处理前后合金的性能及显微组织的变化,结果表明,700℃保温3 h淬火处理后,抑制了合金中的富Er相的形成,合金的磁致伸缩性能从37×10^-6提高到56×10^-6,磁致伸缩的增大是由于合金冷却过程中出现不同的相结构,且具有择优取向的样品性能较好。更多还原

【Abstract】 We studied the magnetic scalability and microstructure of Fe₈₃Ga₁₇Er_0.4 rolling state alloy under different heat treatment methods and compared properties and microstructure of alloy before and after heat treatment. Result shows that 700℃ for 3 h and then quenched,the quenching treatment can inhibit the formation of the alloy Er- rich phase and the scalability of the magnetic alloy can be improved from 37 × 10^-6 to 56 × 10^-6,the increase of the magnetic expansion is due to the different phase structure in the process of the alloy cooling,and has better performance of the sample with the preferred orientation.更多还原
