Abstract Scope |
Metals produced via additive manufacturing (AM) exhibit non-uniform loading responses or anisotropy due to the directional growth of crystals during solidification. Understanding the process parameters involved with the formation of microstructure and anisotropy is critical to the qualification and certification and use of AM parts for high-performance structural applications. One of the primary causes of anisotropy is preferred crystal orientations (crystallographic texture), which can be controlled by altering AM processing parameters. This work presents a study on the texture evolution of AM-built Ti-6Al-4V via neutron diffraction, and demonstrates the influence of varying scan strategy on crystallographic texture at the bulk and local scales as a function of build height. The findings presented here are discussed in the context of improved process-microstructure-property relationships and the production of born-qualified parts. |
