Recent developments in AM technology and AM Standards offer great potential to implement AM produced part in the US Army. Current applications mainly focus on secondary structures or other non-critical applications. The quantitative process-structure-property relationships will be determined with computational modeling with respect to build orientation.ĭESCRIPTION: Additive Manufacturing (AM) is a new production technology that enables reduced manufacturing steps, part consolidation and production of near net shape parts from 3-D model data. The resulting mechanical properties and microstructures will be compared to the traditional Ti-6Al-4V alloys bars, forgings and castings.

These heat treatments are Mill-Anneal (MA), ANNeal (ANN), Solution Treat and Age (STA) and Beta Solution Treat and Overaged (BSOA). Tensile testing, smooth bar high cycle fatigue testing and microstructural analyses are to be performed on Laser Powder Bed Fusion (L-PBF) manufactured near net shape Ti-6Al-4V specimens having four heat treatment types after Hot Isostatic Pressing (HIP).

OBJECTIVE: The key objective of this work is to evaluate the mechanical properties and microstructural characteristics of post-process heat treatments of Additively Manufactured (AM) Ti-6Al-4V alloy including process-structure-property relationships.
