摘要： The invention relates to a method for the production of a martensitic steel sheet having a yield point greater than 1300 MPa. The method comprises the following steps consisting in: supplying a semi-finished steel product having a composition containing, expressed as weight percent, 0.15% ≤ C ≤ 0.40%, 1.5%≤ Mn ≤ 3%, 0.005% ≤ Si ≤ 2%, 0.005%≤ Al ≤ 0.1%, S ≤ 0.05%, P≤ 0.1%, 0.025%≤ Nb ≤0.1% and, optionally, 0.01% ≤ Ti ≤ 0.1%, 0% ≤ Cr ≤ 4%, 0% ≤ Mo ≤ 2%, 0.0005% ≤ B ≤ 0.005%, 0.0005% ≤ Ca ≤ 0.005%, the remainder of the composition being formed by iron and the inevitable impurities resulting from production; heating the semi-finished product to a temperature T
1 between 1050°C and 1250°C and, subsequently, subjecting the heated semi-finished product to rough rolling at a temperature T
2 between 1050 and 1150°C, with a cumulative reduction rate ε
a greater than 100%, such as to obtain a sheet having an austenitic structure that is not totally recrystallised, with an average grain size of less than 40 micrometres and preferably less than 5 micrometres; and cooling the sheet, such as to prevent the transformation of the austenite, at a rate V
R1 greater than 2°C/s to a temperature T
3 between 970°C and Ar3+30°C, and, subsequently, subjecting the cooled sheet to final hot rolling at temperature T
3 , with a cumulative reduction rate ε
b greater than 50%, such as to obtain a sheet that is then cooled at a rate V
R2 above the critical cooling rate.
