Hydrogen Embrittlement Behavior of Plastically Pre-Strained and Hydrogen-Charged low alloy Steel

Keywords

hydrogen concentration, pre-strain, fracture energy, hydrogen embrittlement

Abstract

The paper investigates the effect of high-temperature gaseous hydrogenation of low-alloy 22K steel on its resistance to hydrogen embrittlement (HE). The propensity to hydrogen embrittlement of the studied material was evaluated by determining the hydrogen embrittlement index based on the results of traditional uniaxial tensile tests of hydrogen-free and hydrogen-charged samples. The research was carried out for pre-strain-free and 75% pre-strained samples
