Ti-6Al-4V-xSn (x = 2, 4, and 6 wt.%) alloys were developed for the aerospace application through the near net shaped technique powder metallurgy route. Spark Plasma Sintering (SPS) was used to sinter the samples. The influence of Sn particles on the microstructural characteristics and mechanical properties of titanium alloy was examined through a novel technique called SPS. It has been found that Sn has a strong solid solution strengthening ability in the titanium alloy (Ti6Al4V). Moreover, the addition influences the microstructure and mechanical properties of titanium alloy. With increasing the percentage of Sn content, the density of the samples decreases, and the mechanical properties like yield stress (YS), ultimate tensile stress (UTS), the percentage of elongation and the hardness are greatly varying. From this investigation, it is found that YS, UTS, the percentage of elongation of the samples of Ti6Al4V-2Sn alloy exhibit better values than of Ti6Al4V-4Sn and Ti6Al4V-6Sn alloys, and the hardness of the samples is increasing with the addition of Sn from 2 to 6 %.
