摘要

采用单辊快淬法制备Fe40Co40Zr9B10Ge1和Fe40Co40Zr5Mo4B10Ge1两种非晶合金，并在不同温度下对其进行热处理。利用XRD和VSM两种仪器对合金的微观结构和磁性能进行测试分析，研究Mo添加对Fe40Co40Zr9B10Ge1合金晶化过程和磁性能的影响。结果表明，两种合金在晶化初期均有α-Fe(Co)相从非晶基体析出，但高温热处理后的晶化产物不同，Mo添加减少了高温金属化合物的含量。低于675℃热处理，Mo添加降低了合金晶化过程中析出α-Fe(Co)相的晶粒尺寸和合金的矫顽力。

Abstract:

Fe40Co40Zr9B10Ge1 and Fe40Co40Zr5Mo4B10Ge1 amorphous alloys were prepared by melt-spinning and annealed at different temperatures. The microstructure and magnetic property of the alloys were tested and analyzed by XRD and VSM. The effect of Mo addition on the crystallization and magnetic property of Fe40Co40Zr9B10Ge1 alloy was studied. The results show that α-Fe(Co) phase precipitates from amorphous matrix at the initial stage for two alloys. However, the crystallization products after high-temperature heat treatment are different. The addition of Mo reduces the content of metal compounds at high-temperature. The addition of Mo reduces the grain size of α-Fe(Co) precipitated during crystallization. The addition of Mo also reduces the coercivity.

Key words: amorphous crystallization coercivity
