Abstract

Dislocation structures in the near surface layers of α-Fe produced by repetitively pulsed intense Hf ion beams with doses of 0.23 × 1016 to 24.0 × 1016 ions cm-2 were studied by electron microscopy. Both ion implantation and plasma deposition were used. Under such conditions the maximum impurity concentration of Hf in α-Fe appeared to be 70 at.%, the dose of implanted ions being determined from profile analysis of Hf distribution by the RBS method. A developed dislocation structure is formed by ion implantation in the near surface layer of α-Fe over a depth of 100 μm. The dislocation density reaches its maximum value at a depth of 5-7 μm from the surface and is increased by about 1-2 orders of magnitude from that in the initial state. Static tensions formed in the doped layer play a decisive role in the formation of the dislocation structure.
