Abstract

The results of an investigation of defect structure in α-Fe exposed to high power ion beams are presented. Using positron annihilation and electron microscopy, we have revealed the formation of a dislocation structure, vacancy clusters and vacancy loops in the near surface layer. It is shown that defect formation results in increased microhardness and decreased friction coefficient.
