Resumen:
Purpose ? The purpose of this paper is to present a ribbons production route of composition
Fe78Si9B13 (%at.) using low cost noncommercial scrap materials to obtain usable magnetic cores by
melt spinning technique and their characterization. This way, these may compete with the materials
produced by conventional casting processes.
Design/methodology/approach ? The methodology is to design a master alloy with scrap different
starting compositions, to which Fe is added to get the desired atomic ratio of components. With this
starting alloy, using the method of melt spinning, in its variant of chill block melt spinning, are
achieved amorphous ribbons with desired soft magnetic behavior. Then these ribbons are thermally
treated for achieve nanocrystalline structures to improve the performance in the magnetic cores.
Findings ? The result of this paper shows that it is possible to recycle scrap materials, and re-used
efficiently as components essential in part of electrical components. This way, these may compete with
the materials produced by conventional casting processes.
Research limitations/implications ? The limitation of this work to ensure that the scrap materials
used is reasonably adequate to accomplish obtaining the master alloy, i.e. having reduced impurities.
Practical implications ? The implications are important, because it assures that the components are
recyclable and also high-tech in reference to energy saving that involves the production of amorphous
and nanocrystalline materials in the electric industry. These products may compete with those
produced by conventional casting processes.
Social implications ? The social implications lead to awareness in recycling and energy saving as
an option for social progress in technology.
Originality/value ? The originality of the study is that it takes as a starting point for the final
product (ribbon) noncommercial scrap materials of known composition and the obtained results are
comparable to those that also are manufactured from the pure elements. The control of impurities is
necessary in the production route. This way, these may compete with the materials produced by
conventional casting processes. This process achieved a production with lower cost, high efficient
energy products and high added value
