A method for the production of a slightly metal part, light metal component and an internal combustion engine with cylinder liner from light metal component

摘要

The present invention relates to a process for the production of a slightly metal part, comprising at least the following steps:– Production of a bolt (10) from a hypereutectic high power aluminum alloy with a si - content of 17 – 35 wt..-%;– Deformation of the bolt (10) in a first stage by means of extrusion with a first degree of deformation to a between the hollow profile (20);– Shaping of the between the hollow profile (20) in a second stage by means of extrusion with a second degree of deformation to form an end profile (30), wherein the total degree of deformation over both stages in the order of magnitude of 1: 36 to 1: 90, and the extrusion geometric dimensions, tolerances and / or material properties of the slightly metal part at the end profile (30) are adjusted.The present invention further relates to a light metal component with this process and an internal combustion engine having at least a cylinder liner, which is formed by such a light metal component.
