Additive manufacturing can be used to develop desired microstructures for specific mechanical performance. To reduce variance in properties and quality standardization of processing is required. Understanding microstructure and its relation to mechanical properties during thermal processing can improve the use of AM. This research advances development and standardization of the AM process, specifically for titanium, and investigates the link between processing, structure, and properties.
Commercially pure titanium samples were printed with Directed Energy Deposition, where parameters such as tool path and energy density were varied. The main goal was to identify how processing steps result in residual stresses in a printed material and relate these effects to microstructure, and study the influence of microstructure on mechanical properties. Microstructural differences were observed using nano-indentation, electron microscopy, and electron backscatter diffraction.
