This study was conducted to observe the phase transformation of Ti-35 %Nb-2.5 %Sn during milling for various milling times using a mixing machine and a high-energy ball milling machine (HEBM). In this work, niobium was chosen as the β stabilizer and tin as the reducer of the elastic modulus. The starting materials were blended and milled in a mixing machine (24 h) and a high-energy ball mill machine (1 h, 4 h, and 12 h). The particle sizes and phases of the produced powders were analyzed using XRD, SEM, TEM, and PSD; the titanium was found to be fully transformed from the α phase to Ti the β phase Ti after 12 h of milling.
