Ultrafine ferrite in low carbon steel
TLDR
In this article, the authors have reported the development of a new thermomechanical process which produces ultrafine ferrite (UFF) in hot rolled steel strip, which is the result of a strain induced transformation reaction activated over a significant volume of the austenite.About:

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.

Improvement of the work hardening rate of ultrafine grained steels through second phase particles
TL;DR: In this paper, the work hardening rate of various ultrafine grained steels with different carbon contents was studied, and the increase in the amount of finely dispersed cementite particles leads to an improved workhardening rate, which is sufficiently large to balance the negative effect of grain refinement on ductility.

TL;DR: In this paper, a mathematical model was developed that predicts the final mechanical properties of hot-rolled steels, consisting of submodels for static and metadynamic recrystallisation, grain growth and the transformed ferrite grain size.
