This paper presents a simplified procedure to analyse the Hydrogen Induced Cracking (HIC) of structural steels by means of the Small Punch Test (SPT). Two types of notched specimens were used: one with through-thickness lateral notch and another with surface longitudinal notch. The results for ...
A Proposal Procedure to Estimate the Hydrogen Induced Cracking Growth RateWalter F. GONZALEZJorge L. GONZALEZDiego I. RIVASH.DORANTES R
In our previous report IIW IX-1195-81, a new formula for cracking parameter PHA was introduced in order to analyze and predict the critical conditions leading to various types of hydrogen-induced cold cracking in welded high-strength steels. In this report, the formula for PHA has been given...
Different mechanisms have been explored as possible causes for this effect15, including hydrogen-enhanced localized plasticity16,17, hydrogen-enhanced decohesion18, hydrogen adsorption-induced dislocation emission19, hydrogen-enhanced strain-induced vacancy formation20. For all these potential internal damaging...
[59]. Since saturation over the entire thickness was confirmed for the electrochemical charging procedure (cf. Fig. 6 (a)), hydrogen is present in this central line, and will cause hydrogen induced cracking. Show abstract Experimental and Numerical Investigation of Hydrogen Embrittlement Effect on ...
Fig. 12a shows the analysis of hydrogen accumulation around the hydrogen-induced crack in Fe-C alloy using hydrogen microprint technique (HMPT) after tensile test in hydrogen environment. Fig. 12b,c shows the crack path in the IPF map and the boundary map after ion beam cleaning of the ...
Therefore, in the present study, the effects of helium atom trapping at dislocations and irradiation-induced vacancy-clusters on the hydrogen embrittlement have been investigated. Results Effect of hydrogen on mechanical properties of annealed sample Figure 1 shows engineering stress– engineering strain ...
The energy of hydrogen-induced cracking The energy required for grain boundary cracking is defined as cohesive energy. Yamaguchi et al. [191] calculated the cohesive energy of symmetrical grain boundaries ∑3 (111) of body-centered cubic iron-containing hydrogen by first-principles calculations found...
