Abstract Scope |
Vibratory peening aims to combine both beneficial effects of shot peening and vibratory finishing. This work aims to understand the effect of the process parameters on surface integrity of Ti-6Al-4V. Mill machined and mirror polished specimen were vibratory peened with two different eccentricities and for two different processing times. Surface topography was evaluated using roughness profilometer, optical microscope and white light optical interferometry. The initial surface preparation had the most important effect on the surface roughness after vibratory peening. Mirror polished specimens resulted in the optimum surface finish, given for a given set of process parameters. The increase of processing time for vibratory peening on mill machined specimen allowed to reach the optimum surface finish. Micro-hardness measurements and SEM-EBSD cartographies were performed. It was highlighted that the XRD method is recommended to assess the plastic strain induced by vibratory peening in Ti-6Al-4V. |
