Identification of Twin Formation in Additively Manufactured Stainless Steel by In-situ EBSD

A recent study of additively manufactured austenitic stainless steels (300 series) observed that deformation twinning, which is not typically observed in wrought products, occurs in this material [1]. This was thought to enable higher strength and ductility. To better understand this phenomenon, we focused on two critical questions: when during deformation does twinning begin, and does twinning occur in all grains or is deformation accommodated by a mix of slip and twinning? These questions were addressed by characterizing in-situ tensile tests with scanning electron microscopy (SEM) and electron backscatter diffraction (EBSD).
