Selective laser melting (SLM) is an additive manufacturing technology utilizing a laser beam to melt powder materials together layer-by-layer for 3-dimensional part fabrication. Due to its superior rapid prototyping capability of complex structures, SLM has been widely accepted for industrial applications including aerospace, automotive, and medical devices. However, a more comprehensive understanding on the process-microstructure-properties correlation has not yet been revealed. The metallic additive manufacturing process comprises of non-uniform temperature gradient and rapid thermal cycles that leads to microstructures with porosity and anisotropy, drastically different from their cast or wrought counterparts. Such different microstructural features critically affect the mechanical properties of the additively manufactured parts. Therefore, understanding of microstructure evolution during SLM is crucial to achieve improved process control and provide the performance of laser-fabricated components. This project aims to control the microstructure of Ti-6Al-4V alloys for the next generation additive manufacturing.
