Powder forging of Ti-6Al-4V included in uniaxial die compaction of mixed Ti and Al/V powders, pressureless sintering of the compacts, and warm closed die forging of the sintered preform in the temperature ranges from 900 to 1100C. As the forging temperature increased, the relative density of the specimens is also increased, and the tendency appears to be in an accordance with numerical simulation results by a commercial finite element program. Full densification was found to be achieved when the sintered preform was pressed above the temperature of 960C. Moreover, the mechanical properties were found to be much higher than those of wrought Ti-6Al-4V alloys which appeared to be attributed to the microstructural characteristics of the forged specimen. Consequently, powder forged Ti-6Al-4V connecting rods exhibit superior mechanical strength with moderate ductility compared with the alloys produced by other fabrication techniques.
