【 摘 要 】

Titanium is anattractive material for structural and biomedical applications because of itsexcellent corrosion resistance, biocompatibility and high strength-to-weightratio. The high reactivity of titanium in the liquid phase makes it difficultto produce it by fusion. Powder metallurgy has been shown to be an adequatetechnique to obtain titanium samples at low temperatures and solid-phase consolidation.The production of compacts with different porosities obtained by uniaxial pressingand vacuum sintering is briefly reviewed. Powder particle size control has beenshown to be very important for porosity control. Sample characterization wasmade using scanning electron microscopy (SEM) images.
