Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

An analysis is performed of the structure and phases of porous samples of the 316L austenitic steel obtained via laser 3D printing. Residual δ-ferrite is found (along with austenite) in the sample via transmission electron microscopy. High density of dislocations is observed in the sample as well. ESBD analysis revealed the textureless state of the sample.
