Titanium alloy has been massively used in automotive and aerospace fields, such as Ti-6Al-4V titanium alloy. Further, the emergence of metallic additive manufacturing (AM) technology has been a breakthrough in the workpiece formation, such as selective laser melting (SLM). Besides, additive manufacturing is capable of producing complex metal components with high performance and speed that have fulfilled the mechanical requirements and light structure. A further study on the use of Ti-6Al-4V titanium powder is required, specifically on its mechanical properties and material failure mechanism due to the selective laser melting (SLM) process. The mechanical properties of Ti-6Al-4V titanium alloy rely highly on the phase of its composer, grain morphology, and characteristic length scale, as well as grain orientation (texture). Also, the heat treatment post SLM process also affects the strength of material produced through SLM using titanium alloy. In specific cases, the microstructure study has to be carried out since, in the biomedical implementation, such as in bone-implant on the joining area and wrist, fractures tend to occur. The fracture caused by the imperfect formation process during the melting of Ti-6Al-4V titanium powder or parameter of selective laser melting can be dangerous. This study reviews the failure mechanism of Ti-6Al-4V titanium using selective laser melting. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
