In this study, in situ neutron diffraction experiments were conducted during uniaxial tensile deformation for Fe-4.91Mn-0.092C (mass%). The primary aim was to investigate the change of austenite texture accompanied with the deformation induced martensitic transformation (DIMT). It was observed that grains oriented <001> towards the tensile direction tend to persist during the deformation. Moreover, the fraction of <001> oriented grains increases due to crystal rotation caused by dislocation slip. Grains with <111> towards the tensile direction are consumed more rapidly than those with <001>. These observations are qualitatively reproduced by visco-plastic self-consistent model, additionally considering DIMT to ε martensite. Although ε martensite was not identified in the diffraction pattern obtained in this study, a previous microstructural study indicated the γ→ε→α’ type DIMT for the same material. In contrast, it is known that in low alloyed TRIP steels subjected to tensile deformation, grains with <111> tend to survive, where γ→α’ type DIMT occurs. Based on the results of this study, the orientation that persists after tensile deformation can distinguish between the DIMT mechanisms: γ→ε→α ’ or γ→α ’ type.","PeriodicalId":22340,"journal":{"name":"Tetsu To Hagane-journal of The Iron and Steel Institute of Japan","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135605079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of hydrogen on crack initiation of fracture toughness test has been investigated using a combination of experimental and computational approaches. Tempered lath martensitic steel was subjected to fracture toughness test with monotonically rising load in air and high-pressure hydrogen gas. While crack propagated continuously within grains in air, cracking in hydrogen grew by linking isolated interface failure ahead of a main crack tip. Then, to understand the nucleation mechanism of isolated failure in the presence of hydrogen, the tensile simulations of twist grain boundaries (TGBs) rotated along <110> axis at various angles were conducted using molecular dynamics calculations. While the dislocation emission from TGB rotated 70° is dominant deformation mode in the absence of hydrogen, the rupture along TGB rotated 110° and 170° without stress relaxation due to dislocation emission is dominant deformation mode in the presence of hydrogen. As a consequence, it is indicated that the origin of hydrogen-induced isolated crack initiation in the vicinity of fatigue pre-crack is the rupture along the block boundaries within martensitic structure due to hydrogen-induced inhibition of dislocation emission from GBs.","PeriodicalId":22340,"journal":{"name":"Tetsu To Hagane-journal of The Iron and Steel Institute of Japan","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2022-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86924160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fatigue tests were carried out at ambient temperature around 300 K and a frequency of 50 Hz with a stress ratio of –1. The Fe-C-Mn steel exhibited a comparable hardness and fatigue limit to the water-quenched Fe-0.017C ferritic steel which contains about three times the amount of solute carbon than the Fe-C-Mn steel. In addition, the Fe-C-Mn steel exhibited a comparable coaxing effect to the Fe-0.017C ferritic steel when started from a stress amplitude near the fatigue limit. Crack initiation sites were changed by stress amplitude unlike in the Fe-C ferritic steels. Spe-cifically, intergranular cracks were observed at high stress amplitudes and transgranular cracks were observed at low stress amplitudes near fatigue limit. It was concluded that the Mn addition suppresses intergranular cracking at the low stress amplitudes.","PeriodicalId":22340,"journal":{"name":"Tetsu To Hagane-journal of The Iron and Steel Institute of Japan","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2022-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81365380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
