Abstract: According to aspects of the embodiments, there is provided method and system of using a roller-based deposition process to place two or more powders at some level of precision to build a multi-material, functionally-graded part. Instead of formulating a liquid ink by dispersing the powder feedstocks (metal or ceramic) in some binder-solvent mixture, there is detailed the use of two different types of fluid deposited in a digital manner on the roller surface. The two different types of fluids create a “wetted pixel” that can then capture a specific powder type with an affinity only to that fluid. Alternatives such as electrostatics, electrophotography, and the like are also provided to be used exclusively or with fluids to create an affine pixel to a particular powder type.

Abstract: A method for producing a steel component from a flat steel sheet is provided. The produced steel component includes a substrate and a coating. The method ensures that the steel component has an Hdiff content below a certain level. The low Hdiff content minimizes the risk of hydrogen-induced cracking of the steel component after hot forming, including during subsequent use of the steel component. The Hdiff content in the hot-formed steel component is ensured to be below a certain level by selecting furnace parameters depending on the rolling degree and the sheet thickness of the flat steel sheet.
