| This study examines the structural evolution of Ti-5Sn-3Mn and Ti-10Zr-5Sn-3Mn (all wt. %) alloys during mechanical alloying. In the case of Ti-5Sn-3Mn, XRD results showed minor variation up to 20 h, followed by peak broadening and intensity reduction after 40 h due to grain refinement and strain accumulation. After 60 h, Sn and Mn peaks vanished, indicating their dissolution in the Ti lattice and formation of a β-Ti solid solution, while a Ti(101) peak shift confirmed change in lattice parameter. In the case of Ti-10Zr-5Sn-3Mn alloy, Zr addition promoted faster Sn dissolution and β-phase formation at shorter milling time. Both alloys developed stable nanocrystalline structures as crystallite size decreased with milling time. Moreover, a gradual reduction in particle size of the mill product occurred by increasing the milling time as revealed by scanning electron microscopy. Furthermore, particles reduction was associated with chemical homogeneity and uniform distribution. | ||
