Information received from the surface evolution. Because hydrogen alloy composition of hydrogen in solid γ. And dissolving solution Hydrogen γ - ε changes in mechanical properties after being charged with a new significant information about the processes occurring in the course of the charging and subsequent deformation of steel during testing hydrogen ions. The
first, on the basis of changes in the crystal structure. One can conclude that Plastic deformation occurring during charging Cathodic hydrogen is from Figure 2 that the results are in. steelcr15ni40. This is why this steel has few resources of plastic on the test machine follows (see Figure 3), the plastic deformation caused by corrosion is an important argument in the debate about the nature of hydrogen. εγ -
changes above rigsbee Be the first to point out the similarities in the characteristics of the species. Hydrogen and ε - martensites in steel Ostend Laws c. .
From this observation atrens et al. have calculated the concentration of hydrogen caused by the austenite steel and concentration of hydrogen by a factor of 10 within the surface layer 5 μ m, then it is generally accepted that ε -. Marten site was created due to the stress caused by sharp hydrogen concentration profile during charging. Cathodic
at the same time as the calculation of Ab initio effect of hydrogen on the electron structure in the absence of any stress, ε-phase is stable above thermodynamics in comparison with γ - Step H / mz1 in steel CrNi Witiatan and mother. Even small bits of manganese in the steel crmn is variable, though. In practice, however, charging the steel γ - ε very small plots of hydrogen. It also involves dissolving the homogenization of hydrogen that occurs H / M1 / 40.8 between hydrogen gas and steel cr18ni16mn10 not what γ - ε convert data confirmed unanimously. Plastic deformation strain is not the real reason for γ - ε changes in the cathode during charging. And this is why hydrogen induced stress and ε - martensites are similar
so. The second part of this study. The data layer of silicon to hydrogen concentration in the skin that seem to contradict each other (see Table 2) increasing the concentration of hydrogen on the surface, if I drop content. I was down in line with the enthalpy of hydrogen migration in austenite, however, the reduction of the concentration of hydrogen. Which should slow down To help hydrogen is reversed, and the third related to the malfunction of the h-martensite ε on hydrogen embritlement.
The band with cheese added a ε - Marten sites (see Table 2), which is expected to decrease. Because Sri stacking fault energy austenite steel However, as Figure 3 by Sri adding hydrogen. cr15ni25 embrittlement of steel, which is at variance with the information about the positive effect of silicon on the resistance of a solid steel in the Americas to decompose hydrogen. The above mentioned collision can be removed if you consider that next. The process can take part in courses of hydrogen ions and subsequent mechanical tests:
(1) H-epsilon martensite is expected to occur in Ostend Laws c. With maximum hydrogen content,
(2) plastic deformation during mechanical testing that can come with γ - ε further conversion. To test these expectations. The diffraction of X-rays are generated cr15ni25 steel after charging and testing mechanical followed (Figure 4) shows that the proportion of ε - Marten sites due to be increased. In the course of a draw Quantitative data of ε - Marten site after the mechanical testing of steel and hydrogen ions cr25ni25 cr15ni25si2 are shown in Table 2, in other words, mechanical testing of hydrogen ions cr15ni25 steel will come with traveling. The result is increased compared with plastics cr15ni25si2 steel at a fraction of ε - martensite transformation site. insignificantly The tensile
