Abstract:Additive manufacturing (AM) of metals has drawn attention by both researchers and industries in recent decades for replacing aspects of conventional steel fabrication due to lessened cost and higher production flexibility. However, the characterization of the properties of AM steel remains scarce. This paper presents the ultrasonic determination of the second-order elastic constants of 17-4 PH steel produced using powder bed fusion AM. Both longitudinal and shear wave phase velocities are used to solve for the… Show more
