Abstract
The behavior of (alpha) -Fe alloys with molybdenum and tungsten carbides and oversize substitutional atoms under reactor irradiation has been investigated to study the possibility to substitute the molybdenum atoms for tungsten ones in order to create low activated steels. Computer simulation of collision cascades was used to study the damage of iron targets with Mo and W impurities and carbides under irradiation. It was found that at the ballistic stage of radiation damage the tungsten carbides are damaged to a higher degree and can be destructed more effectively than molybdenum carbides because of differences in interatomic potentials.
