Abstract: The invention relates to a method for producing components using a powder that has been melt-atomised in an inert gas atmosphere from an aluminium or Al alloy with integrated hard materials, in particular from MMCs (metal matrix composites), reinforcing particles being added to the molten and atomised metal, in particular aluminium or an aluminium alloy, during or consecutive to the spraying process, and subsequently the powder particles being compressed by way of an SPS method in order to produce a component or a semi-finished product.

Abstract: A cylinder liner for use in a cylinder crankcase includes a liner body having at least one end face, and a material strip. The material strip is affixed to the liner body and projects axially from the at least one end face of the liner body.

Abstract: The invention concerns a method for producing a substance during which an aluminum base alloy is produced that has a content of 5.5 to 13.0% by mass of silicon and a content of magnesium according to formula Mg [% by mass]=1.73×Si [% by mass]+m with m=1.5 to 6.0% by mass of magnesium, and has a copper content ranging from 1.0 to 4.0% by mass. The base alloy is then subjected to at least one hot working and, afterwards, to a heat treatment consisting of solution annealing, quenching and artificial aging. The magnesium is added based on the respectively desired silicon content according to the aforementioned formula. The material obtained by using the inventive method comprises having a low density and a high strength.

Abstract: A method for producing, by forming techniques, an undercut profile in the outer circumferential face of cylinder liners to be cast in place in a crankcase, characterized by the introduction of a bracing inner core into the cavity of a cylinder liner, the introduction of the cylinder liner equipped with bracing inner core into a first forming die equipped on its working faces with a serrated profile, the pressing of the first forming die against the outer circumferential face of the cylinder liner, thus producing a complementary profile in the outer circumferential face, the introduction of the cylinder liner equipped with bracing inner core into a second forming die equipped on its working faces with a smooth surface, and the pressing of the second forming die against the outer circumferential face of the cylinder liner equipped with the complementary profile.
