Quantitative Evaluation of Fish Eye Defects in Structural Steels

Popis výsledku v původním jazyce

The paper is devoted to the study of hydrogen embrittlement (HE) in thick plates made of two structural steels ? VStE500 and A516Gr70. HE was studied by means of tensile tests on specimens taken in two different orientations ? longitudinal (L) and through-thickness (TT). Specimens were hydrogen charged electrolytically prior the tensile tests. After tensile tests, quantitative fractographic analysis was performed using so called systematical scanning. HE manifested itself mainly by the formation of fisheyes ? defects initiated on non-metallic inclusions. Stereological parameters of fish eyes differed mainly as a function of the specimen orientation. Fish eyes were more numerous and larger in TT direction. Stereological parameters of the fish eyes werein a good agreement with the observed changes of the mechanical properties of the studied steels.
