| Abstract Scope |
Hot Isostatic Pressing (HIP) can be a useful tool to increase the density of metal Additively Manufactured (AM) parts. This post-process route can have significant impacts on the microstructure and material properties such as strength, ductility, and fatigue resistance. Many metal AM materials, especially those fabricated using wire based directed energy deposition (W-DED) process, have a high degree of anisotropic behavior resulting from the columnar prior β microstructure. Titanium based alloys can be highly sensitive to these massive grains as the prior β boundaries are primary nucleation sites for grains promoting the formation of continuous α across the length of the boundaries. This talk discusses preliminary efforts to utilize HIP as a means to reduce variability in mechanical properties and its effects on the anisotropic behavior of W-DED Ti-6Al-4V products. |
