| Abstract Scope |
The mechanical properties of additively manufactured (AM) Ti-6Al-4V components can vary greatly depending on a number of factors and these factors include chemistry, AM processing conditions, and post-processing. In this work, we investigated the underlying mechanisms that drives the resulting mechanical properties and anisotropic behavior observed within AM Ti-6Al-4V. A series of tensile specimens were machined and tested from coupons that were produced via various AM processes that included directed energy deposition and powder bed fusion processes. The microstructure of the AM coupons were characterized to help develop an empirical strength model. Using this model and comparing the mechanical behavior results from Ti-6Al-4V specimens that were produced by various AM processes and in various post-process conditions, a fuller picture was obtained on the significant factors from the AM processing and post-processing that impacted the microstructure and the resulting mechanical behavior. |
