A manifold structure is formed using ultrasonic additive manufacturing and machining. The manifold structure includes a body having a base plate and a cover plate that define a flow passage therebetween, and a plurality of walls that segment the flow passage into a plurality of channels, wherein each of the walls has a height extending from the base plate to the cover plate and a non-linear length that is elongated relative to a width of the wall and extends in a direction normal to the height of the wall. The walls are wavy in shape to provide enhanced rigidity and stiffness during lamination over the channels.

A method for producing a structural component, which has different component sections, from a high-strength alloy material. The structural component to be produced is divided into at least two component sections which differ with respect to their requirement profiles when the structural component is later used, wherein one component section must meet a higher requirement profile with respect to occurring loads, and the at least one other component section must meet a lower requirement profile. In a first production step for producing the component section with the higher requirements, a blank is brought to near-net-shape or net-shape by a massive forming process in some regions. To form the at least one component section with the lower requirement profile, a body in the form of a pre-manufactured part, which corresponds to said component section, is arranged on at least one surface region in the form of a substrate, which has not yet been brought into its near-net-shape or net-shape by the massive forming process, and is bonded to the blank in at least one following step, and/or said component section is attached to the provided surface region of the blank by a generative production method in order to also bring the aforementioned regions of the massive-formed component section to a near-net-shape. The semi-finished product produced in this manner, as a completed preform, is then brought to its net-shape in one or more steps.

A method for laser-marking an iron-based sintered body includes a first step of forming with a first laser beam a plurality of dotted recesses with a predetermined depth in an identification mark area of a surface of an iron-based sintered body, and a second step of flattening with a second laser beam the surface within the identification mark area other than the dotted recesses. The first laser beam has an irradiation energy per unit area greater than an irradiation energy per unit area of the second laser beam.
