Prediction of Yield Strength of Selective Laser Melted Ti–6Al–4V Alloy Using Melt Pool Geometry

Abstract

Abstract Additive manufacturing (AM) method has attracted huge interest in the past decade due to its ability in building complicated geometries with a much lower cost than conventionally produced parts. In AM, the final mechanical properties can be controlled by the AM process parameters. In other words, the AM process parameters control the amount of energy that is transferred into the powder and consequently the resulting microstructure. In this study, the correlation between melt pool geometry and mechanical properties of selective laser melted (SLM) Ti–6Al–4V samples is investigated.
