Powder Metallurgy (PM) Titanium has great potentials as low-cost alternative for Ti manufacturing, but the use of conventional PM processes for producing Ti products is also limited due to reasons related to either that the properties are not as satisfactory as that of equivalent wrought materials, or the cost advantage is not as significant as it was expected. Therefore, the main challenge of developing PM Ti is to increase performance to cost ratio. Reduction of costs and improvement of final products must involve every step of the entire process. This article attempts to assemble a set of processes by selecting individual unit processes that when combined synergistically could offer the optimum performance to cost ratio. This set of processes include using low cost powders, using automatable near-net-shape compaction techniques, and using sintering using sintering technologies that can produce parts with very fine grain sizes, thus satisfactory mechanical properties, in as-sintered state.
