A high-strength steel sheet according to the present invention comprises, by weight percent, 10.0-15.0 % of Mn, 6.0-9.0% of Al, 0.5-2.0% of Cr, 0.8-1.6% of C, 0.001-0.01% of N, and further comprises 0.02-0.1% of V, 0.005-0.015% of Nb, and 0.005-0.02% of Mo, or 0.1-0.5% of TiAl particles. The high-strength steel sheet has a complex tissue containing austenite and fine k-carbide with an average particle diameter of 10-500 nm. |
