Abstract
Amorphous metallic alloys (AMAS) have found wide application in various fields. Laser is used to modify materials. In this work, we have prepared an amorphous metallic alloy with composition Fe77Co21Si2 using the melt spinning method. The prepared specimens have irradiated by a Nd:YAG laser at 1064 nm, with various fluences to investigate the corresponding induced change. The structures of specimens are verified by X-ray diffraction (XRD) before and after laser irradiated. Then magnetic parameters are measured using a vibrating sample magnetometer. Morphology reference and laser treated samples are investigated by the scanning electron microscope (SEM). The use of laser beam of relatively low energy, but with a subsequent overlapping of heated areas, resulted in a much more homogeneous structure in the heated areas of the ribbon. These measurements show that initially the magnetic properties are altered due to laser processing. The surface alteration was being simultaneously monitored by laser induced breakdown spectroscopy (LIBS).
