Introduction

CONCURRENT ENGINEERING methodologies drastically reduce or eliminate the need for trial and error methods in the design of process tooling or prototype components. Both the materials data and the analysis tools are readily available for product design activity. However, the process design activity has, in general, been hampered by a lack of readily available data on the mechanical behavior of materials under the conditions encountered during manufacturing. Furthermore, the mechanical behavior of metal powders is fundamentally different than that of metallic solids leading to the necessity to develop new process analysis tools tailored to this unique behavior. This article provides an update on process models used in the production of components by metal powder die compaction, powder injection molding, and hot isostatic pressing. More information on modeling of die compaction is in the article "Mechanical Behavior of the Metal Powders and Powder Compaction Modeling" in this Volume.
