• ABSTRACT: The present stage of scientific and technological development is characterized by wide-ranging and diverse applications of the energy of high-energy fluxes (HEFs), such as electron and photon beams. The fundamental advantage of HEFs over the conventional heat sources is the possibility to achieve high energy density on the surface of the component treated, which explains the wide use of HEFs for welding, heat treatment, surface modification, fabrication of wear- and corrosion-resistant coatings, etc. The use of HEFs for modification of metal and alloys widens the capabilities of the techniques for improving their physical and mechanical properties. In recent years, as the studies on the development of novel materials have intensified, hybrid techniques of HEFs treatment began to be widely applied, whereby additional alloying is performed in the treated zone thus achieving a substantial effect on the physical and mechanical properties of the materials processed. This work presents results HEFs modification and welding of metals and alloys obtained in recent years at the Laboratory of Physical Technologies at the Institute of Electronics of the Bulgarian Academy of Sciences
