| Abstract Scope |
Surface Optimized Diffusion Alloys (SODA) allow for late-stage customization of steel products. In this process a steel sheet is coated with a slurry which contains the desired alloying additions. The coated steel sheet is then batch annealed to alloy the substrate surface. This has the potential to revolutionize steel production because it eliminates the need for the specialized infrastructure needed for making steels with high additions of elements such as Cr, Mn and Si. In addition, because the alloying additions are introduced after cold-rolling, it is possible to avoid rolling issues associated with certain alloying additions. Most importantly, the new compositionally graded steels produced in this way allow new combinations of properties that could not be achieved using homogenous materials. In this presentation, the use of SODA to produce corrosion resistant medium-Mn steel sheet is discussed. |
