摘要:
Provided is a Fe—Mn—C-based twinning-induced plasticity (TWIP) steel which includes 13 wt % to 24 wt % of manganese (Mn), 0.4 wt % to 1.2 wt % of carbon (C), and iron (Fe) as well as other unavoidable impurities as a remainder, is manufactured by caliber rolling, has a microstructure including elongated grains that are elongated in a rolling direction, and has an average grain size of the elongated grains in a direction perpendicular to the rolling direction of 1 μm or less.
