摘要： A process for fabricating a steel sheet is provided. The process includes soaking a steel sheet. The steel has a composition including iron, carbon, manganese, silicon, aluminum, sulfur, phosphorus and nitrogen and at least one metallic element X chosen among vanadium, titanium, niobium, molybdenum, and chromium. A quantity Xp of metallic element under the form of carbides, nitrides or carbonitrides is, by weight: 0.030%≤Vp≤0.40%; 0.030%≤Tip≤0.50%; 0.040%≤Nbp≤0.40%; 0.14%≤Mop≤0.44%; or 0.070%≤Crp≤0.6%. The soaking step occurs under a pure nitrogen or argon atmosphere with a dew point lower than −30° C. at a soaking temperature θ between 250 and 900° C. and with a dynamic circulation of a regenerated atmosphere.

摘要： The present invention provides an assembly of an aluminum-based element and an element made of steel provided on at least one of the surfaces thereof with a metal coating. The metal coating is made of a zinc-aluminum-magnesium alloy including from 2.3% to 3.3% by weight of magnesium and from 3.5% to 3.9% by weight of aluminum. The remainder of the metal coating is zinc, inevitable impurities and possibly one or more additional elements selected from among Si, Sb, Pb, Ti, Ca, Mn, Sn, La, Ce, Cr, Ni or Bi. The coated surface of the steel element is in at least partial contact with the the aluminum-based element. The contact is brought about by a layer of adhesive or sealant having a thickness of less than 5 mm. The present invention also provides a part for a vehicle including at least one assembly and a vehicle.
