Plastic accommodation at homophase interfaces between nanotwinned and recrystallized grains in an austenitic duplex-microstructured steel
Ivan Gutierrez-Urrutia,Ivan Gutierrez-Urrutia,Fady Mamdouh Fawzy Archie,Dierk Raabe,F.K. Yan,Nairong Tao,Kathy Lu,Kathy Lu +7 more
TL;DR: The smooth profile of the orientation gradient amplitude within the first 10 grain layers indicates a gradual plastic accommodation of the homophase interfaces upon straining, resulting in an enhanced ductility of the single phase duplex-microstructured steel.
