Abstract

A limited number of features that comprise the more wholistic materials state of electron beam, powder bed additively manufactured Ti-6Al-4V have been investigated. Coupling scanning electron microscopy and orientation microscopy, the microstructure and texture of samples produced using different AM scan strategies have been studied at various positions along the build height of the samples. Both the qualitative and quantitative results, including parent beta grain orientation, alpha lath texture, and predominant type of microstructure (colony vs basketweave), and their length scales are included. Both the scan strategy used for the build and the time between proximal molten pool passes have been shown to significantly influence the resulting microstructure and texture. © 2020, The Minerals, Metals & Materials Society and ASM International.
