摘要：
The high strength-to-mass ratio and the appreciable corrosion resistance make the Ti-6A1-4 V alloy used in aerospace, automotive, maritime and biomedical applications. In this work the quasi-static behavior of this light alloy and its axial fatigue resistance in air, air + beeswax coating, paraffin oil, 3.5 wt% NaCI solution and various water-methanol solutions are presented in order to understand the effects of the medium and of the load. The contribution of the stress concentration factor K-t, calculated by means of finite element modelling, is investigated. A SEM (scanning electron microscopy) analysis was carried out in order to evaluate the micro structural modifications due to the environments and cyclic loads.
