High dislocation density–induced large ductility in deformed and partitioned steels
TL;DR: The deformed and partitioned (D and P) process produced dislocation hardening but retained high ductility, both through the glide of intensive mobile dislocations and by allowing us to control martensitic transformation.

Fatigue behaviors of AISI 316L stainless steel with a gradient nanostructured surface layer
TL;DR: In this article, a gradient nanostructured (GNS) surface layer was formed on AISI 316L stainless steel and the mean grain size is ∼30nm in the topmost surface layer and increases with depth.

Segregation engineering enables nanoscale martensite to austenite phase transformation at grain boundaries: A pathway to ductile martensite
Dierk Raabe,Stefanie Sandlöbes,J. Millán,Dirk Ponge,Hamid Assadi,Michael Herbig,Pyuck-Pa Choi +6 more
TL;DR: In this article, a phase field model was proposed to predict the kinetics of phase transformation at segregation decorated grain boundaries, showing that strong interface segregation of austenite stabilizing elements (here Mn) and the release of elastic stresses from the host martensite can generally promote phase transformation.

The morphology and crystallography of lath martensite in Fe-C alloys
TL;DR: In this article, the morphology and crystallography of lath martensite in Fe-C alloys containing various carbon contents from 0.0026 to 0.61% were studied by analyzing electron back scattered diffraction patterns in scanning electron microscopy and Kikuchi diffraction pattern in transmission electron microscope.

Overview no. 96: Evolution of F.C.C. deformation structures in polyslip
TL;DR: In this article, the authors investigated the microstructural evolution during polyslip in f.c.m.d. metals and showed that there are differences in the number and selection of simultaneously acting slip systems among neighboring volume elements of individual grains.

New discoveries in deformed metals
TL;DR: In this article, the authors have shown that the microstructural evolution follows a universal pattern of grain subdivision from the macroscale to the nanometer scale, and that the similarity between the behavior of materials undergoing different deformation patterns forms the basis for future research and development encompassing traditional as well as new materials and processes.

The morphology of martensite in iron alloys
G. Krauss,A. R. Marder +1 more
TL;DR: In this article, the main structural differences between the two major types of martensite in ferrous alloys are discussed in terms of their possible effects on the plastic deformation mechanisms which must occur in the parent austenite and product martensites during transformation.
