6. CASE STUDIES

The following case studies represent a variety of products made by forging. They have been chosen to illustrate most of the forging processes, a variety of the alloys, and many of the principles set forth in the preceding chapters. Some of the products were readily formed using only industry standard technology; others required special capabilities. Some of the products are of recent origin, while some were developed more than a decade ago. All are current in the sense that they illustrate the capability of the forging industry to supply products with improved performance, reduced cost or reduced manufacturing and assembly problems compared with alternate processes.
