Journal ArticleDOI
Hydrogen-assisted failure in a twinning-induced plasticity steel studied under in situ hydrogen charging by electron channeling contrast imaging
TL;DR: In this paper, the authors investigated the hydrogen embrittlement of a Fe 18Mn-1.2%C (wt.%) twinning-induced plasticity steel, focusing on the influence of deformation twins on hydrogen-assisted cracking.
Journal ArticleDOI
Effect of hydrogen and stress concentration on the notch tensile strength of AISI 4135 steel
TL;DR: In this article, the quantitative relationship between notch tensile strength and diffusible hydrogen content has been investigated for the AISI 4135 steel at 1320 MPa by means of a slow strain rate test on circumferentially notched round bar specimens with stress concentration factors of 2.1, 3.3 and 4.9.
Journal ArticleDOI
Continuous recrystallization in austenitic stainless steel after large strain deformation
TL;DR: In this paper, the static restoration mechanisms operating during annealing were studied in a 304 steel with strain-induced submicron grain structures, where the initial microstructure with an average grain size of about 03 μm was developed by large strain deformation at 873 K.
Journal ArticleDOI
Alloy Design, Combinatorial Synthesis, and Microstructure–Property Relations for Low-Density Fe-Mn-Al-C Austenitic Steels
Dierk Raabe,Hauke Springer,Ivan Gutierrez-Urrutia,Franz Roters,Michael Bausch,Jae Bok Seol,Motomichi Koyama,Pyuck-Pa Choi,Kaneaki Tsuzaki +8 more
TL;DR: In this paper, the authors present recent developments in the field of austenitic steels with up to 18% reduced mass density, which are based on the Fe-Mn-Al-C system.
Journal ArticleDOI
Work hardening associated with ɛ-martensitic transformation, deformation twinning and dynamic strain aging in Fe–17Mn–0.6C and Fe–17Mn–0.8C TWIP steels
Motomichi Koyama,Motomichi Koyama,Takahiro Sawaguchi,Taekyung Lee,Chong Soo Lee,Kaneaki Tsuzaki,Kaneaki Tsuzaki +6 more
TL;DR: The tensile properties of carbon-containing twinning induced plasticity (TWIP) steels and their temperature dependence were investigated in this paper, where three deformation modes were observed during tensile testing: martensitic transformation, deformation twinning, and dynamic strain aging.
