Abstract
By mechanical testing, metallographic and SEM analyses, the influence of hydrogen on the frangibility of modern high-strength dual phase DP- and multiphase TRIP-steels was studied. Results of studying of microstructural and mechanical properties of thermomechanically controlled processed TMCP-steels before and after hydrogenation indicate that TRIP-steel has higher resistance to HE, which can be seen from its fine-grained microstructure with no cracks and also from unchanged mechanical performances after hydrogenation.
