摘要： An automotive engine component and method of producing the same. The method uses dynamic magnetic compaction to form components with non-axisymmetric and related irregular shapes. A die is used that has an interior profile that is substantially similar to the non-axisymmetric exterior of the component to be formed such that first and second materials can be placed into the die prior to compaction. The first material is in powder form and can be placed in the die to make up a first portion of the component being formed, while a second material can be placed in the die to make up a second portion of the component. The second material, which may possess different tribological properties from those of the first material, can be arranged in the die so that upon formation, at least a portion of the component's non-axisymmetric exterior profile is shaped by or includes the second material.

摘要： Cam lobe packs and methods of producing the same. The method uses a tool made up of an insert disposed within a sleeve such that both are responsive to a dynamic magnetic compaction (DMC) pressure source. The insert defines a substantially axisymmetric exterior surface and a cam lobe-shaped interior surface that can receive a compactable material such that upon DMC, the material is formed into the shape of the cam lobe. The sleeve is disposed about the insert and defines a substantially axisymmetric exterior surface such that an axisymmetric compaction imparted to the sleeve by the DMC pressure source forms the desired shaped cam lobe. The tool is configured such that individual tool members corresponding to one or more of the cam lobes can be axially aligned so that an aggregate interior surface is formed that defines an exterior surface profile of a camshaft being formed.

摘要： An automotive engine valve stem, engine valve and method of producing both. The valve includes a head and a stem joined to the head. Lightweight, high-temperature materials, such as titanium-based materials may be used to make up at least a the majority of the valve. These materials are combined with fabrication techniques that may vary between the head and the stem, where at least a part of the valve is made by dynamic magnetic compaction. While a majority of the stem may be made from a titanium-based powder material, its tip may be made of a high strength hardened material, such as a steel alloy. The valve head may be made by single press and sintering, double press and sintering, forging and machining, forging and sintering, and dynamic magnetic compaction and sintering.
