Low temperature macro- and micro-mechanical behavior of an ultrafine-grained metastable 304 austenitic stainless steel investigated by in situ high-energy X-ray diffraction

In situ neutron diffraction reveals the effect of Cu micro-alloying on low-temperature tensile properties of TWIP steels

“…High-Mn (15-30 wt.%) steels are exhibiting ever-growing importance as structural materials in multiple cryogenic applications from liquid natural gas storage/transmission to superconducting magnets due to their excellent strength-ductility balance, desirable strength/weight ratio [1], and lower cost compared to other austenite steels [2], and 9 % Ni steels [3]. Recently, more prominent strengthening effects and excellent strength-ductility combinations of high Mn steels in a low-temperature range were reported [4][5][6].…”
