Now, there is a lot of interest in the development of nanocrystalline and amorphous materials, that present high mechanical resistance combined with good ductility, opening great technological perspectives for the processing these of materials. Due to its versatility, the amorphous alloys have been showing to have properties that can be used in several areas, as in memory of computers, applications in several types of transformers for potency and electronic uses. The technique used to obtain of amorphous alloys in this work, it went to of rapid solidification starting from the liquid state, for melt spinning. The processing of the ribbons of was made in two stages, initially the coalition of the alloy was accomplished by magnetic induction, later on, the alloy was submitted the new remelting to improve the homogenizationand soon after, the amorphous metallic ribbon was produced, used of the high cooling rate, around 10³°C/s. During the processing, the obtained ribbon came amorphous and with a thickness around 25µm.
