The paper presents the results of the pulsed beam effect on the structure and phase composition of zirconium alloy. Such treatment is demonstrated to lead to forming of complex morphology martensite in the surface layer of the alloy. The processes of hydrogen absorption by zirconium alloy with modified surface have been studied. Modification of the samples is found to reduce the amount of hydrogen, absorbed by the volume of zirconium alloy during hydrogenation.

It has been shown that electron beam treatment of silumin is accompanied by the formation of multilayer submicro-and nanocrystalline structure and result in increasing the microhardness of the surface layer (towards the core) is ~ 1.5 times up to 2 GPa. Investigation of cross-sections of the samples also showed an increase of microhardness of the surface layers up to 50 μm and 70 μm under the best conditions of irradiation on "GEZA-1" setup and "SOLO" setup respectively.
