Powder Metal Parts for Automotive Applications 850458

In line with the present trend to make structural parts at or near net shape, the powder metallurgy process is being studied more and more by automotive design and materials engineers who are finding an increased application for this energy and cost saving process. Many new applications, besides some older ones, of P/M by domestic and overseas automotive manufacturers are presented outlining material specifications and service conditions for engine, transmission and chassis parts. In addition to conventional porous P/M parts, examples of high tensile fully dense precision hot formed P/M parts are presented which give superior service life and lighter weight than conventional wrought steel. Despite the decreased size and weight of future automobiles, an increased number of applications of powder metal is likely to result in a greater usage of P/M materials per vehicle.
