Abstract
With the steep growth of metal Additive Manufacturing (or 3D printing), evaluating and fine-tuning its fabrication process has become a crucial part of its development. Mapping of elastic properties of additively manufactured samples was successfully performed with the highly adaptable Resonant Ultrasound Spectroscopy technique. The general method used so far for elastic moduli measurements of additively manufactured alloys (stress-strain tensile testing) only allows the finding of the Young's modulus, and that, with moderate accuracy. Here, we report on elastic constants of additively manufactured Ti64 and CL 80CU alloys measured with resonant ultrasound. The moduli found are generally slightly lower than those for their wrought version. As expected, the elastic properties are more or less uniform within a given volume, depending on the fabrication parameters or location with respect of the build direction. The behavior of the alloys with heat treatment and proton irradiation was also tested and will be reported elsewhere.
