In this paper, Ultrasonic Nanocrystal Surface Modification (UNSM) and Laser Shock Peening (LSP) were used to study the improvement in corrosion resistance, biocompatibility and fatigue behavior of a low-modulus beta Titanium alloy Ti-35Nb-7Zr-5Ta-0.3O (wt %). The solution treated samples were subjected to UNSM and LSP treatments. The microstructure after UNSM and LSP is characterized by optical, scanning electron microscope (SEM) and transmission electron Microscope (TEM). Potentiodynamic test shows improvement in corrosion resistance in Hank’s solution after UNSM & LSP. Nanoindentation and tensile tests were used to determine mechanical properties which also show improvement in material properties after LSP and UNSM. Three point bending fatigue tests were also performed to study improvement in fatigue life through S-N Curves. The increase in surface hardness caused by severe plastic deformation and high magnitude of compressive residual stresses leads to the improvement in fatigue life.
