Electron Microscope Study of Phase Transformations in 316L Austenitic Steel Produced via Laser 3D Printing

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. E...

Zusammenfassung: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.
