The influence of pulsed laser radiation on the structure and mechanical properties of amorphous Fe(Ni, Co, Mn)MoSiB films has been investigated. The structural changes caused by the irradiation were studied by X-ray diffraction and the microhardness of the initial and irradiated samples was measured by the Vickers method. It was established that small additions of Ni, Co, or Mn have a significant influence on the crystallization process of the irradiated alloys. Irradiation leads to an increase of the microhardness for some values of pulse energy.
