  • Patent number: 10378089
    Abstract: Methods for using a mold to partially harden semifinished products, which are comprised of hardenable steel and have at least partially an open-profile or closed-profile cross section, may involve a number of steps. For example, such methods may involve heating regions of a semifinished product above an AC1 temperature, positioning the semifinished producing in a mold, positioning an active mold cooling element adjacent to or in contact with the heated regions of the semifinished product, and cooling the regions of the semifinished product at a defined cooling rate so that a hardened microstructure in the cooled regions. These methods and corresponding devices provide low cost solutions that dispense with complete hardening of semifinished products and/or employing welded connections to provide various mechanical properties.

  • Patent number: 10357830
    Abstract: The method for the production of an element subject to wear, comprising a metal matrix and at least a core of hard material. The method provides a first step in which a temporary aggregation structure is prepared with at least partly open pores, which volatilize or in any case eliminate at least partly when subjected to heating. A second step in which, on the whole internal and external surface of said temporary aggregation structure, a liquid mixture of a binder with metal powders which contain hard elements or their precursors is uniformly distributed. A third step in which the temporary aggregation structure is deteriorated by means of a thermal action of controlled heating, so as to take at least part of the temporary aggregation structure to evaporation, rendering free a volume inside the core, and to consolidate the mixture according to the conformation of the temporary aggregation structure. A fourth step in which the core is disposed in a mold so as to only partly occupy the free volume of the mold.
