Abstract

The sintering-compaction process is one of the important methods of Ti-Al alloy component manufacturing. It is essential to obtain a thorough understanding of the mechanics involved in the process, such as the load-compaction relationship, void evolution, residual stress and plastic deformation. A unit cell micromechanics approach is used in this study to investigate the load-compaction relationship for various materials under different temperatures. The friction effect is evaluated and void evolution is observed. A formula based on the principle of soil mechanics is developed to describe the phenomenological pressure-compaction responses of materials during the sintering-compaction process. © IMechE 1997.
