Influence of annealing treatment on micro/macro-texture and texture dependent magnetic properties in cold rolled FeCo–7.15V alloy
چکیده انگلیسی


• This paper describes the macro- and micro-texture of Fe–Co–7.15V after rolling and annealing conditions.
• The grain boundary character distribution (GBCD) and microstructures of the material were analyzed using EBSD.
• The texture dependence magnetic properties of Fe–Co–7.15V were studied.

The influence of annealing treatment on macro- and micro-texture of cold-rolled FeCo–7.15V ferromagnetic ultra-thin foils were studied. The microstructural studies performed by field emission scanning electron microscope (FE-SEM) showed the formation of paramagnetic precipitations ((Fe, Co)3V) during annealing. During cold rolling of the FeCo–7.15V magnet, the texture components of type (113)[11¯0], (001)[11¯0], (111)[11¯0], and (111)[12¯1], all related to α and γ-fibers were formed. X-ray diffraction (XRD) and local texture measurements performed by electron backscatter diffraction (EBSD) were made on the annealed samples. Both methods revealed that the recrystallized samples have texture characterized by γ fiber component, when the recovered samples were characterized by α fiber component. The grain boundary character distribution (GBCD) and microstructures of the material were analyzed using EBSD. The experimental results showed that annealing at 870 °C for 2 h resulted in a high frequency of twin boundaries. The maximum CSL density could reach 7.5% under annealing conditions: at 870 °C for 2 h. Finally, in order to investigate the texture influence on the magnetic properties, magnetic properties of the samples were measured using a vibrating sample magnetometer (VSM). The results showed an improvement in remanence induction (Br) with the formation of hard axis <100>.
