Synergistic deformation pathways in a TWIP steel at cryogenic temperatures: In situ neutron diffraction

L Tang, L Wang, M Wang, H Liu, S Kabra, Y Chiu… - Acta Materialia, 2020 - Elsevier
High manganese steels are promising candidates for applications in cryogenic
environments. In this study, we investigate the mechanical and microstructural responses of
a high manganese twinning induced plasticity (TWIP) steel at a low-temperature range (from
373 to 77 K) via in situ neutron diffraction qualification and correlative microscopy
characterization. During plastic deformation, stacking fault probability and dislocation
density increased at a faster rate at a lower temperature, hence, higher dislocation density …
