The Selective Layer melting process (SLM) is an additive manufacturing process widely used in recent years for the production of titanium alloy components. Although this technology is encountering growing success, it suffers from a lack of repeatability that hinders its development on a larger scale. Besides, anisotropic properties and early breaking are often observed on the manufactured parts. The control of these properties is made difficult because they depend to many factors such as metallurgical parameters of input powder and both process and microstructural parameters.
Our work is mainly focused on developing a comprehensive understanding of the process-micro/nanostructure-properties relationships of Ti-6Al-4V titanium alloys produced by SLM.
From an original approach at the phases scale, it is shown that is possible to discriminate the key process parameters that control the mechanisms of both microstructure formation and defects generation and thus the resulting in-use properties.
