To this end, the starting powders were characterised by dilatometry, differential thermal analysis and XRD. Green samples were obtained by cold uniaxial pressing, and the evolution of the microstructure over the sintering temperature range 900-1400 °C was studied. The variation of the final density and mechanical properties with the sintering temperature was considered. Based on the study carried out, it can be stated that more reliable powders are needed to open the titanium market to new applications. A relative density of 95% and diverse microstructural features and mechanical properties equivalent to those of biomedical devices can be obtained by the pressing and sintering route.application/pdfeng© ElsevierTi 3Al 2.5VTi 6Al 4VTitanium P/MPrealloyed (PA)Blending elemental (BE)Flexural strengthMechanical behaviour of pressed and sintered titanium alloys obtained from prealloyed and blended elemental powdersresearch articleIngeniería IndustrialMaterialesQuímica10.1016/j.jmbbm.2012.05.013open access2938Journal of the Mechanical Behavior of Biomedical Materials14AR/0000012485
