Thermomechanically influenced dynamic elastic constants of laser powder bed fusion additively manufactured Ti6Al4V

This paper reports the dynamic elastic constants of laser powder bed fusion additively manufactured Ti6Al4V alloy by recently developed effective bulk modulus elastography technique and compares them with static evaluated using nanoindentation technique. With this technique, two ultrasound frequencies (10 MHz 20 MHz) were employed, which distinctly identified spatially varying density in while comparing to wrought Ti6Al4V. The spatial resolution scanned region significantly improved at frequency. 5%–8% lower than obtained for In addition, present study moduli Ti6Al4V, solutionized water quenched microstructural examination scanning electron microscopy revealed a high internal twins within martensite laths contrary scarcely twinned lath origin such defect was realized thermo-mechanical computational model that predicted rapidly changing alternating tensile-compressive stresses range 49–720 MPa that, turn, affected constants.
