Abstract Scope |
Recently developed effective bulk modulus elastography (EBME) technique was employed on laser powder bed fusion fabricated and wrought Ti6Al4V samples. The corresponding dynamic elastic constants were compared and evaluated with respect to the static elastic constants measured using the nanoindentation technique. The EBME technique produced maps of elastic constants from the scanned region, with an improved spatial resolution with increased ultrasound frequency. The dynamic elastic constants were (5-8 %) lower than the static elastic constants for both additively manufactured and wrought Ti6Al4V. In addition, the EBME technique coupled with shear wave velocity measurement inside the material identified the bulk crystallographic texture response, wherein significant attenuation of shear wave velocity occurred at 45o and 90o orientations of shear wave plane with respect to the build plane of the printed Ti6Al4V. In contrast, wrought Ti6Al4V reflected an isotropic response. |
