摘要: Abstract The composite consists of disordered and ordered iron–platinum (FePt) alloys was induced by nanosecond pulsed laser (NPL) irradiation. process investigated high-voltage electron microscopy (laser-HVEM), transmission (TEM), X-ray diffraction (XRD) analyses. structural transformation upon NPL irradiation monitored laser-HVEM imaging, with the structure being modified in a short second after one pulse. XRD analyses revealed expanded contracted lattice distances before irradiation, respectively. According to TEM results, surface FePt transformed from fct fcc strain
