Abstract
The sintering-compaction process is one of the important methods of Ti -Al alloy component manufacturing. It is essential to obtain a thoroug h understanding of the mechanics involved in the process, such as the load-compaction relationship, void evolution, residual stress and plas tic deformation. A unit cell micromechanics approach is used in this s tudy to investigate the load-compaction relationship for various mater ials under different temperatures. The friction effect is evaluated an d void evolution is observed. A formula based on the principle of soil mechanics is developed to describe the phenomenological pressure-comp action responses of materials during the sintering-compaction process.
