Dynamic Response of Wrought and Additively Manufactured 17-4 Stainless Steel
ORAL
Abstract
17-4 stainless steel is a martensitic alloy with good corrosion resistance that can be precipitation hardened to achieve high strength. These properties, along with its ability to be cast, additively manufactured (AM) or wrought processed, have made it a common alloy in many engineering applications. A series of uniaxial-strain, plate-impact experiments were performed to investigate the thermodynamic and constitutive response of both wrought and AM 17-4 stainless steel to stresses near 20 GPa. Measurements of the Hugoniot, Hugoniot elastic limit (HEL), and spallation strength were obtained. The results indicated that post-processing heat treatment is the dominate factor in determining its elastic and failure response, while its thermodynamic response varies little between fabrication methods.
