Abstract
Titanium and its alloys are very popular for various applications. They are the most widely used materials for biomedical applications. Titanium-based materials have shown excellent biocompatibility, as well as mechanical properties and corrosion resistance. The high fatigue life of this material is often demanded, therefore fatigue testing is necessary. Additive manufacturing (AM) is an innovative, widely investigated method for the production of metal components. AM allows the possibility of producing complex shaped components with near to net shape. Selective laser melting (SLM) is one of the most promising AM techniques. This research explores the fatigue behaviour of titanium alloy Ti6Al4V, produced by SLM. Different conditions and surface preparations for additive manufactured specimens were investigated by fatigue testing and then compared to each other. The aim of this research is to explore the influence of surface machining and processing by hot isostatic pressing (HIP) on the fatigue properties of the SLM produced components.
