摘要: Rapid thermokinetics associated with laser-based additive manufacturing produces strong bulk crystallographic texture in the printed component. The present study identifies such a effect on elastic anisotropy laser powder bed fused Ti6Al4V by employing an effective modulus elastography technique coupled ultrasound shear wave velocity measurement at frequency of 20 MHz inside material. combined identified significant attenuation from 3322 ± 20.12 to 3240 21.01 m/s 45 $$^\circ$$ and 90 orientations plane respect build block Ti6Al4V. Correspondingly, reduction 48.46 0.82 46.40 0.88 GPa was obtained these orientations. Such is rationalized based $$\alpha ^\prime$$ variants within prior columnar $$\beta$$ grains additively manufactured
