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.
Journal ArticleDOI
Mechanical Properties and Retained Austenite in Intercritically Heat-Treated Bainite-Transformed Steel and Their Variation with Si and Mn Additions
TL;DR: In this paper, process peculiarities and functions of alloying elements, such as Si and Mn, were studied for improving formability of steel sheets with mixed microstructures, and the holding time in the bainite transformation range varies with temperature, depending on the activation energy of C diffusion in austenite, and shifts to longer times with an increase of Si or Mn additions.
