The results of analysis of elemental and phase composition, defect structure and micro-hardness profile of carbon steel subjected to combined treatment consisting in its electroexplosive doping with copper and following electron beam treatment have been introduced. Cardinal change of the structure and multiple increase (in 5…6 times towards the sample core) of surface micro-hardness is determined.
Представлены результаты анализа элементного и фазового состава, дефектной структуры и профиля микротвердости углеродистой стали, подвергнутой комплексной обработке, состоящей в ее электровзрывном легировании медью и последующем электронно-пучковом облучении. Выявлено кардинальное изменение структуры и кратное (в 5…6 раз по отношению к сердцевине образца) увеличение микротвердости поверхности.
