Notes:
Titanium is an attractive material for structural and biomedical applications becauseof 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 becamefragile from hydrogenation process and were able to be used to obtain compacts withdifferent porosities by uniaxial pressing and sintering without applied pressure. Sincehydrogen dissolves easily in titanium to form titanium hydrides which have a stronginfluence on the microstructure coarsening and mechanical properties, the study of theporous 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 wereinvestigated by scanning electron microscopy. High resolution x-ray was used to characterizethe present phases. Evaluation of the porous titanium hydrides mechanical behavior wasrealized by flexion assay performed at three points
