Abstract
A new friction powder compaction (FPC) process is introduced for compacting commercially pure titanium powder. The FPC process is very simple and energy-efficient since it requires only a rotating tool plunged into an aluminum plate with a hole filled with titanium powder, and no external heat source is necessary. The sintering of the powder is mainly achieved by the friction heat and pressing load generated by the rotating tool in the aluminum plate and powder. The microstructure and Vickers hardness of the compacted titanium powder were investigated. It was shown that titanium powder was satisfactorily compacted by the FPC process.
