Titanium is an attractive material for structural and biomedical applications because of its excellent corrosion resistance, biocompatibility and high strength-to-weight ratio. Power metallurgy was used in this work to prepare 3D porous titanium. The powders became fragile from hydrogenation process and were able to be used to obtain compacts with different porosities by uniaxial pressing and sintering without applied pressure. Since hydrogen dissolves easily in titanium to form titanium hydrides which have a strong influence on the microstructure coarsening and mechanical properties, the study of the porous compacts hydrogenation was carried out by hydrogenation at different temperatures (870 K up to 1070 K) in a hot filament reactor. Titanium surface morphology changes were investigated by scanning electron microscopy. High resolution x-ray was used to characterize the present phases. Evaluation of the porous titanium hydrides mechanical behavior was realized by flexion assay performed at three points.
