Abstract
Using nuclear-physical and physical methods, we investigate the modification process along the penetration depth of a low energy high current electron beam. The analysis of the defect structure shows vacancy clusters (divacancies, trivacancies, loops) and an increased dislocation density in this modified layer. Computer calculations show that the thickness of the melted layer increases with the energy flow density and that the energy flow density determines the boundaries of the direct heat attack of a high current electron beam. The increased hardness of the modified layer is related to the increased dislocation density.
