Recrystallization Behavior of a Laser Additive Manufactured Austenitic Stainless Steel

JOM. Journal of the Minerals, Metals & Materials Society

Smith, Thale; Sugar, Joshua D.; Schoenung, Julie M.; San Marchi, Chris

Directed energy deposition (DED) and forged austenitic stainless steels possess distinct microstructures, but may exhibit similar mechanical properties. In this study, annealing is used to evolve the microstructures of these materials, and scanning electron microscopy techniques are used to probe the similarities and differences of the microstructure-property relationships. A strong correlation between geometrically necessary dislocation (GND) density and hardness is observed for the forged material. Finally, a more complex relationship is observed in the DED material and is attributed to the thermally driven dissolution of the solidification microstructure.
