О возможности влияния на когезивную прочность границ включение-матрица стали

The effect of laser action on the formation of microcracks on the inclusion–matrix boundaries during plastic deformation was investigated. It was shown that the local microwelding under laser action contributes to increase the cohesive strength of these boundaries. It was established the influence o...
