Abstract

The application of the Electric Resistance Sintering (ERS) process has the advantage of rapid densification and sintering, but it needs to analyse the influence of the parameters on the microstructure and final mechanical properties in a titanium alloy. In an ERS equipment, different current intensities will be applied to atomized powders of Ti-6Al-4V using the commercial pure Ti (CP) with the same parameters as the reference material. Its effect on the microstructure obtained along the thickness of the sample will be analysed. The mechanical characteristics will be determined by tensile and cantilever bending tests, together with maps of microhardness distribution that allows relating the mechanical behaviour with the microstructure applying backscattered electron diffraction techniques (EBSD).
