Abstract

In this research we investigated the influence of hydrogen on the dynamic strength and phase transition in SAE 1020 steel. Exposure of carbon steel to hydrogen creates gaseous methane in the sample according to the reaction Fe3C + 4H è CH4+ 3Fe. Plate impact experiments were carried out in gas gun or powder gun to shock compress the samples to pressures below and above the bcc-hcp (a-e) phase transition, respectively. The Hugoniot elastic limit, phase transition pressure and spall strength were obtained from free surface velocity measured by VISAR. It seems evident from our experiments that the spall strength increases at pressures above the phase transition. The hydrogen treatment did not find to influence the material HEL, a-e phase transition or the spall strength.
