Abstract
⺠A twinning-induced plasticity steel showed degradation of uniform elongation by decreasing deformation temperature. ⺠Intergranular and ε/αⲠboundary cracking, and fracture associated with ε-martensite were observed at 123 K. ⺠The cryogenic tensile properties were improved with decreasing grain size. ⺠One of the important reasons of the improvement was clarified to be suppression of formation of ε-martensite.
