Possibilities of electric resistance method in study of metals and alloys irradiated to a high doses

On the base of metals and alloys and reactor core materials fulfilled its task after high neutron dose and charged particles irradiation the electric resistance method possibilities are shown. It is determined that in the pure metal with BCC-structure (α-Fe and Mo) and TiAl alloy the point defects and its fine clusters and defect areas are mostly generating on atomic cascade shifts places partly relaxing into the dislocation loops. The loops contribution in electric resistance increase does not excess 3-4 and 1.6 % relatively for BCC-metals and TiAl alloy. The addition of impurity leads to impunity atom - radiation defect complex formation. The martensite decay in the U-7 hardened steels is carried out during the process of high power proton damage accompanying with the carbon isolation from the solids solution and dispersion carbide phase particles generation. In the materials of the WWR-K reactor control rod (12Cr18Ni9Ti, SAV-1), EhP-172 steel the process of radiation induced impurities redistributions has been carried out with its isolation from solid solution in the form of the fine phase on the grain boundaries or other preferable discharge
