Abstract Scope |
Ti-6Al-4V is an alloy with wide ranging applications in fields such as aerospace engineering and medical implants due to its high strength, durability, and good corrosion resistance. This study intends to predict and compare cyclic plastic behavior in both traditionally manufactured and additively manufactured Ti6Al4V. Both isotropic and kinematic hardening parameters are extracted and included in the models. An initial comparison of hardening parameters and its relationship with the microstructural features are presented. As suspected, powder bed manufactured material experiences less hardening as compared to the conventionally manufactured Ti6Al4V. A combined hardening model involving Voce’s Non-Linear Isotropic hardening and Chaboche’s Kinematic hardening are utilized. The FEA model is then used to generate the hysteresis loop, verify using available experimental data and compare the fatigue life between traditional and additively manufactured Ti6Al4V. |
