| description | A steel sheet having a composition comprising, by weight: 0.010% = C = 0.080%, 0.06% = Mn = 3%, Si = 1.5%, 0.005% = Al = 1.5%, S = 0.030%, P = 0.040%, Ti and B such that: 3.2% = Ti = 7.5% and (0.45xTi) - 1.35 = B = (0.45xTi) - 0.43, optionally Ni = 1 %, Mo = 1 %, Cr = 3%, Nb = 0.1 %, V = 0.1 %, the remainder being iron and unavoidable impurities resulting from the smelting. The steel sheet has a structure consisting of ferrite, at most 10% of austenite, and precipitates comprising eutectic precipitates of TiB2, the volume fraction of TiB2 precipitates with respect to the whole structure being of at least 9%, the proportion of TiB2 precipitates having a surface area lower than 8 µm2 being of at least 96%.
L'invention concerne une tôle d'acier ayant une composition comprenant, en poids : 0,010 % = C = 0,080 %, 0,06 % = Mn = 3 %, Si = 1,5 %, 0,005 % = Al = 1,5 %, S = 0,030 %, P = 0,040 %, Ti et B tels que : 3,2 % = Ti = 7,5 % et (0,45xTi) 1,35 = B = (0,45xTi) 0,43, éventuellement Ni = 1 %, Mo = 1 %, Cr = 3%, Nb = 0,1 %, V = 0,1 %, le reste étant constitué de fer et d'impuretés inévitables résultant de la fusion. La tôle d'acier a une structure consistuée de ferrite, d'au plus 10 % d'austénite, et de précipités comprenant des précipités eutectiques de TiB2, la fraction volumique des précipités de TiB2 par rapport à la structure totale étant d'au moins 9 %, la proportion des précipités de TiB2 ayant une aire inférieure à 8 µm2 étant d'au moins 96 %. |
