通过高能球磨技术制备了Fe78 Si13B9磁性非晶合金粉体,采用XRD和DSC分析了Fe78Si13B9非晶合金粉体的相组成、玻璃转变温度Tg、开始晶化温度Tx和晶化峰温度Tp;利用放电等离子烧结(SPS)技术在不同烧结温度下制备了块体磁性非晶纳米晶合金试样,利用XRD、SEM、Gleeble3500、VSM等分析了不同烧结温度下烧结块体试样的相转变特性、微观形貌、力学性能和磁学性能.结果表明,在500 MPa的烧结压力下,随着烧结温度的升高,烧结试样中的非晶相开始逐渐晶化,烧结试样的致密度、抗压强度、微观硬度、饱和磁化强度均显著提高;在500 MPa的烧结压力和823.15 K的烧结温度下,获得了密度为6.6 g/cm3,抗压强度为1500 MPa,饱和磁化强度为1.3864 T的非晶纳米晶磁性材料.
