Grain size estimation from transformation kinetics
25
TL;DR: In this article, a method for estimating the grain size of a newly formed phase is presented for isothermal and continuous cooling transformations in which the new phase nucleates homogeneously, on the parent grain boundary surface or grain edges.

Phase Transformation from Fine-grained Austenite
TL;DR: In this paper, the grain size ratio of fine-grained austenite and ferrite, d α /d γ, increases by refining grain size, which results in an increase of hardness.

Mesoscale simulation of deformed austenite decomposition into ferrite by coupling a cellular automaton method with a crystal plasticity finite element model
TL;DR: In this paper, the uniaxial hot compression results given at the coordinates of integration points of finite element mesh, namely the local stored energy of deformation and the crystallographic orientation, are simulated based on the crystal plasticity theory.

A cellular automaton investigation of the transformation from austenite to ferrite during continuous cooling
TL;DR: In this paper, a cellular automaton model has been employed to investigate the transformation from austenite to ferrite in low carbon steels during continuous cooling, where local concentration changes are incorporated into a nucleation or growth function, which is utilized by the automaton in a probabilistic fashion.

Analytical modeling of post-printing grain size in metal additive manufacturing
TL;DR: In this article, an analytical model for postprinting grain size prediction in metal additive manufacturing is presented, where the solution of a moving point heat source for the convection-diffusion equation, which is utilized to describe the thermal equilibrium during the additive manufacturing process, is deduced to calculate the temperature distribution in the build part.

Grain size estimations from the direct measurement of nucleation and growth
TL;DR: In this article, the authors report in situ transmission-electron-microscopy experimental methods that assess independently the nucleation and growth rates of crystallizing grains, and the results from these experimental methods verify the theoretical models that were posed several decades ago.

The kinetics of grain boundary nucleated reactions
TL;DR: In this paper, the authors derived rate laws for transformations in which the new phase nucleates on grain boundary surface, grain edges, or grain corners, and in which a new phase grows with constant radial velocity.
