As Additive Manufacturing (AM) rapidly transitions from small laboratory production to real world applications, the correlation between microstructure, mechanical properties and processing parameters needs to be fully understood. In Electron Beam Melting (EBM) a number of processing parameters can be adjusted with each having an effect on the microstructure of the final component. In addition, layer preheat and print location also impact sample microstructure causing multidirectional microstructure gradients throughout the sample. In this study Ti-6Al-4V powder was used to build complex shape component and the goal is to correlate the effect of processing parameters, feature size of the component, and print location in an EBM Ti-6Al-4V complex component, on the microstructural evolution. An EBM printed workpiece will be sectioned into metallographic samples for detailed microstructural analysis using optical microscopy, scanning electron microscopy in conjunction with energy dispersive x-ray spectroscopy, and electron backscatter diffraction analysis.
