Improvong alloys exploitation characteristics under powerful ion beams action

Methods of positron annihilation, X-ray diffraction analysis, mass spectroscopy of secondary ions, Auger-electron spectroscopy and metallographic investigations were used to study structures of high-speed R6M5 steel, T14K8 hard alloy and KNT-16, TN-20 tungsten-free alloys, irradiated by heavy-current carbon ion beams. Modified layer of complex structure of 50-100 mm thickness forms on the surface of samples under investigation irradiated by powerful ion beam. All structural changes taking place in the layer result to improvement of alloy exploitation characteristics: 1.5-2 time increase of microhardness and 2.2-3.5 time elevation of resistance to cutting as compared to reference check samples
