Dynamics of defects accumulation during hydrogen charge of titanium and stainless steel

Abstract

The hydrogen influence on dynamics of defects formation in VT1-0 titanium and 316- stainless steel was studied. The electrolytic charge by hydrogen in LiOH+H2O solution were performed at a current density 0,5-1 A/cm2. Optical and raster electron microscopy, have revealed a considerable amount of the defects on a sample surface which have appeared after enrichment with hydrogen. For stainless steel, as opposed to titanium, at time of hydrogen charge less than 1 hour and current densities up to 1 A/cm2 surface erosion is not detected. The studying of metals bulk defects were performed by positrons annihilation method. The results of measurement of a positron lifetime have shown that about 150 microns depths the fundamental contribution (up to 90 %) is determined by single vacancies and dislocation. The hydrogen in stainless steel is actively connecting with carbides on borders of grains, therefore there is exhibiting of borders grains. The obtained results allow making a conclusion that a bulk destruction of metal grains is not occurs.
