Abstract
Electric Resistance Sintering (ERS) is a low-cost alternative to Spark Plasma Sintering (SPS). In the developed process the duration of the cycles is very short (seconds) and without protective atmosphere. These features allow an easy industrialization of the process. This paper shows the processing of different titanium alloys by ERS and the effect of the type of powder and composition in the densification of the alloys. The characterization of the products includes the microstructural analysis, EBSD, crystallographic phases by XRD, elastic modulus and bending strength. In addition, oxygen content of the obtained materials was analyzed in detail considering the parameters of the process. It was possible to obtain full densification of the compacts and mechanical properties show interesting results.
