“…When the hydrogen atoms permeate into the metal the travel through the crystal lattice along microstructural channels or through innerstitial lattice sites [5,6,7]. The majority of these sites are ordinary sites described by the normal enthalpy of solution with respect to the atmosphere of hydrogen where the lattice is in contact [4].…”

“…The reduction of area is the change in the load-bearing cross-sectional area at fracture normalized by the initial cross-sectional area, defined by equation (5). Elongation at fracture is the percentage increase in length of the coupon during the test, defined by equation (6). Lower values of elongation and reduction of area indicate lower ductility.…”

Zaleski, Tania M., "Investigation of laser peening effects on hydrogen charged stainless steels" (2008). In the unlikely event that the author did not send a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion. This study investigated the effect of laser peening on hydrogen penetration into metal alloys. Three areas were studied: laser peening, hydrogenation, and hydrogen detection. This study demonstrated that laser peening does not reduce the hydrogen permeation into a stainless steel surface nor does it prevent hydrogen embrittlement. The effect of laser peening to reduce hydrogen-assisted fatigue was unclear. ® UMI

“…however, most research on the hydrogen-induced degradation of materials over the past 40 years has paid insufficient attention to two points that are crucially important in the elucidation of the true mechanisms. One is that in many investigations, hydrogen content was not measured directly, either in specimens designed for internal hydrogen studies or at occluded crack tips, and second that although there have been numerous studies that quantified the influence of hydrogen on fatigue-crack growth, few have been based on microscopic observations; indeed, a large majority of studies have only examined the influence of hydrogen on tensile properties or properties under static loading [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33].…”
