    Abstract: An aerostructure component (6) comprises a core (10) sandwiched between two skins (7, 8), each skin comprising at least one ply (e.g. 9a) of a plurality of elongate reinforcing elements in a metal matrix (36) and the core comprising a plurality of hollow spheres (11) in a metal matrix (37). The component (6) is inherently both lightweight and strong, prevents the ingress of moisture, contains embedded thermal insulation and is electrically conductive. Such properties make it suitable for the formation of a wing box cover or a wing box itself.

    Abstract: A structural component having an internal support structure extending between outer wall portions of the component with one or more compartments included within the support structure. The support structure has support members including internal walls positioned between and/or defined by the compartments. At least one support member connects between the outer wall portions of the component to enhance the structural integrity of the component. The structural component, including the internal support, are cast from a molten material, and in some cases the support members of the internal support structure are formed with a rectilinear configuration. In some cases the cast structural component is a container and the one or more compartments are configured to store a fluid, such as a gas or a liquid. One or more preforms can be used to form a container and may be retained or eliminated from the container after casting.

    Abstract: The present disclosure relates to a wear part having high wear resistance and strength and a method of making the same. The wear part is composed of a compound body of cemented carbide particles cast with a low-carbon steel alloy. The low-carbon steel alloy has a carbon content corresponding to a carbon equivalent Ceq=wt%C+0.3(wt%Si+wt%P) of about 0.1 to about 1.5 weight percent. In another embodiment the wear part could include a body with a plurality of inserts of cemented carbide particles cast into a low-carbon steel alloy disposed in the body. A method of forming a high wear resistant, high strength wear part includes the steps of forming a plurality of cemented carbide inserts by encapsulating cemented carbide particles with a molten low-carbon steel alloy to cast a matrix of cemented carbide particles and low-carbon steel alloy, the low‐carbon steel alloy having a carbon content of and about 1 -1.5 weight percent. Each of the plurality of cemented carbide inserts are coated with at least one layer of oxidation protection/chemical resistant material. The plurality of inserts are directly fixed onto a mold corresponding to the shape of the wear part. The cemented carbide inserts are then encapsulated with the molten low- carbon steel alloy to cast the cemented carbide inserts with the low-carbon steel alloy.

    Abstract: Method for the production of an element subject to wear (10), comprising a metal matrix (14) and at least a core (12) of hard material. The method provides a first step in which a temporary aggregation structure (17) is prepared with at least partly open pores, which volatilizes or in any case is eliminated at least partly by the presence of the molten metal. A second step in which, on the whole internal and external surface of the temporary aggregation structure (17), a liquid mixture of a binder with metal powders which contain hard elements or their precursors is uniformly distributed, and dried. A third step in which the core (12) is disposed in a mold (16) so as to only partly occupy the free volume of the mold (16). A fourth step in which a molten metal material is cast in the mold (16), which metal melts the temporary aggregation structure (17) and occupies the free volume and the volume that it makes free, both inside and outside the core (12), so as to anchor to the latter and thus form a single body.
