An optimum of toughness values and the yield strength ratio Rp0.2/Rm can be found in which a cooling from a second final rolling temperature, more particularly ?Ar3, of the second rolling procedure to a first temperature between 250 and 500° C., more particularly 300 to 450° C., is carried out at a first cooling rate in a first stage after the second rolling procedure, and a cooling to room temperature is carried out at a second cooling rate in a subsequent second stage, wherein a straightening procedure, more particularly a hot straightening procedure, is carried out after the first stage, more particularly during the second stage, and wherein the first cooling rate is >the second cooling rate.

Abstract: A heavy plate and thermomechanical treatment method are disclosed for a starting material, more particularly a slab ingot, for the production of a heavy plate consisting of a steel alloy. In order to be able to achieve advantageous mechanical characteristics in the heavy plate, it is proposed for a multi-stage cooling with optionally at least one straightening procedure to take place after the final forming in that a cooling from a second final rolling temperature, more particularly ?Ar3, of the second rolling procedure to a first temperature between Ar3 and Ar1 is carried out at a first cooling rate in a first stage after the second rolling procedure and a cooling from the first temperature to a second temperature <Ar1 is carried out at a second cooling rate in a subsequent second stage, where the first cooling rate is < the second cooling rate.

Abstract: Methods for graphene-assisted fabrication of a surface on a substrate are disclosed herein. In an exemplary method, fabricating an etched surface on a substrate includes, depositing at least one layer of graphene on the surface on the substrate, patterning the deposited layer of graphene, and exposing the surface on a substrate to an acid to etch the surface on the substrate. The method can further include forming the layer of graphene from graphite. In some embodiments, the layer of graphene is formed by mechanically exfoliating the layer of graphene from the graphite. Alternatively, the layer of graphene can be formed by chemically exfoliating the graphene from the graphite, or other carbon materials, and/or utilizing vapor deposition to form the layer of graphene from the graphite, or other carbon materials.
