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.

A metal matrix composite to high tolerate wear as a property has been produced by infiltration casting of a Fe Alloy and a spinel ceramic by using a material design for i) metal transport phenomena conditions, ii) predefined wetting and capillarity and iii) processing child insert/mother casting methodology to produce a final casting in shape and form to meet the needs of a mining end user.

A metal-ceramic bonded substrate is such that a heat dissipating face is formed in a spherical protruding form, because of which contact pressure with a thermally conductive grease when attaching a heat dissipating fin to the heat dissipating face is high, and high heat dissipation can be secured. Also, by an overflow portion communicating with a metal base portion formation portion being provided farther to an outer side than an external form of the metal-ceramic bonded substrate in an interior of a casting mold, an overflow portion residue is restricted by the casting mold when causing molten metal to solidify and cool, because of which warping deformation occurring because of a difference between linear expansion coefficients of a metal material and a ceramic material can be restricted, and a casting defect such as a running defect in a molten metal flowing process, cold shut, a ripple mark, can be restricted.
