| dc.description.abstract | In direct metal additive manufacturing, the ability to predict and control as-deposited microstructure can reduce the need for post-processing and speed up the qualification process. In this work, a microstructure process map is presented for deposition of single beads of Ti-6Al4V using an electron beam wire feed process. Further, comparison with a previously developed process map for melt pool geometry control demonstrates that indirect control of Ti-6Al-4V solidification microstructure (prior beta grain size and morphology) is possible through direct, real time melt pool dimension control. These approaches for microstructure prediction and control can be extended to additional additive processes such as electron beam powder bed processes. | en_US |
