000256393 520__ $$aWe propose a new method for manufacturing hollow titanium parts by the powder metallurgy route and temporal space holder technique. A pellet of space holder powder is firstly pressed in a die. The pressed pellet is placed inside a pouring of titanium and space holder powder mixture in another die of a larger size. The whole assembly is pressurized and compacted. The removal of space holder material by decomposition or by dissolution and subsequent sintering results in a powder part with an internal hole and porous walls. In the present work, titanium powder and ammonium hydrogen carbonate powder were used as the base and space holder material, respectively. The thermal decomposition of ammonium hydrogen carbonate was used to remove it. An example of the proposed method implementation is described in detail. Tentative application fields of the developed technology are discussed.
