A method for producing a liquid phase sintered aluminum alloy member, includes: a compacting process of compacting a raw material powder containing an aluminum alloy powder containing at least one element selected from Si, Mg, Cu, and Zn, with the balance being Al and unavoidable impurities to form a green compact; a sintering process of subjecting the green compact to liquid phase sintering to give a sintered body; a softening process of subjecting the sintered body to a heat treatment to give a softened material; a straightening process of sizing the softened material to give a straightened material; and an aging process of subjecting the straightened material to a heat treatment to give an aged material in which precipitates are formed.

Raw material powder containing metal powder as a main component is molded to form a metal powder molded body (3), and the metal powder molded body (3) is sintered to form a metal substrate (3). Further, a lubricating member (4) is made of an aggregate of graphite particles (13), and at least a part of a bearing surface (11) is formed of the lubricating member (4). The lubricating member (4) is fitted into the metal powder molded body (3). After that, the metal powder molded body (3) is sintered, and at this time, the lubricating member (4) is fixed onto the metal substrate (3) with a contraction force (F) generated in the metal powder molded body (3).

The invention relates to a method for production of a sintered component (2), comprising the steps: making available an iron-based powder having chromium; filling the powder into a powder press; pressing the powder to form a green compact; sintering the green compact to form the sintered component (2); post-compacting the sintered component (2); hardening the sintered component (2). Sintering is carried out in a decarburizing atmosphere, and the sintered component (2) is moved, for surface-compacting, along an axis (3), from a first matrix opening (6) in the direction of a second matrix opening (13) of a matrix tool (1), which opening lies opposite the first matrix opening (6) along the axis (3), wherein the sintered component (2) passes through multiple matrix sections (7-11) of the matrix tool (1) during this movement, and, in this regard, a surface region of the sintered component (2) is compacted, for which purpose an inside diameter (17) of the matrix sections (7-11) that follow one another becomes smaller in the pressing direction, and the individual matrix sections (7-11) are disposed in such a manner that a subsequent matrix section (7-11) of the multiple matrix sections (7-11) directly follows the corresponding preceding matrix section (7-11), in each instance, in the pressing direction.

A method of manufacturing a sized powder metal component having improved fatigue strength. The method includes the sequential steps of solutionizing a sintered powder metal component and quenching the sintered powder metal component, sizing the sintered powder metal component to form a sized powder metal component, re-solutionizing the sized powder metal component, and ageing the sized powder metal component. The sized powder metal component made by this method, in which the component is re-solutionized between sizing before ageing, can exhibit exceptional improvements in fatigue strength compared to components prepared similarly but that are not re-solutionized.
