摘要
利用Fluxing提纯处理和J-Quenching技术相结合的方法成功制备了最大尺寸为1.2 mm的Fe_(25)Co_(25)-Ni_(25)Cr_5P_(10)B_(10)高熵块体非晶态合金,并对它的磁热性能进行的表征和研究,以探讨高熵效应对非晶态合金磁热性能的影响。目前的高熵块体非晶态合金的居里温度为572 K。在外加磁场为1.5和5 T时,它的最大等温磁熵变和制冷能力的值分别为0.66 J/(kg·K),42.9 J/kg和1.88 J/kg,136.1 J/(kg·K)。与其它非晶态合金磁热性能的对比显示,高熵效应对非晶态合金磁熵变似乎并没有明显影响,但高熵非晶态合金磁熵变随温度变化曲线显示了较大的半高宽温度区间。
In this work, Fe_(25)Co_(25)Ni_(25)Cr_5P_(10)B_(10) High-entropy bulk metallic glasses(HE-BMGs) with a maximum diameter of 1.2 mm were prepared by combination of fluxing treatment and J-quenching technique. Its magnetocaloric effect(MEC) has been investigated and the effect of high entropy on the magnetocaloric properties of amorphous alloys was studied. The Curie temperature of this HE-BMG was 572 K. The peak values of the magnetic entropy change and refrigerant capacity(RC) of the Fe_(25)Co_(25)Ni_(25)Cr_5P_(10)B_(10) HE-BMG were 0.66 J/(kg·K), 42.9 J/kg and 1.88 J/(kg·K), 136.1 J/kg, respectively, under the applied field of 1.5 and 5 T. Compared of the magnetocaloric properties with other amorphous alloys, the high entropy effect did not have obvious effect on the magnetic entropy change of HE-BMGs. However, the magnetic entropy change curves showed a larger full width at half maximum temperature(ΔT_(FWHM)).
