The Time Cone Method for Nucleation and Growth Kinetics on a Finite Domain
TL;DR: The Kolmogorov-Johnson-Mehl-Avrami theory is an exact statistical solution for the expected fraction transformed in a nucleation and growth reaction in an infinite specimen, when nucleation is random in the untransformed volume and the radial growth rate after nucleation was constant until impingement as discussed by the authors.

Atomistic simulations of interactions between the 1 / 2⟨111⟩ edge dislocation and symmetric tilt grain boundaries in tungsten
TL;DR: In this paper, the authors present results of atomistic simulations of interactions between an edge dislocation and three symmetric tilt grain boundaries in body-centred cubic tungsten.

Ledge structure and the mechanism of θ' precipitate growth in AlCu
U. Dahmen,K. H. Westmacott +1 more
TL;DR: In this paper, a model of precipitate plate growth for the PtC interstitial alloy system is extended to substitutional systems and compared with observations on θ′ precipitation from Al-4% Cu.

The kinetics of the internal nitriding of Fe-2 at. pct Al alloy
TL;DR: In this article, the formation of coherent AlN precipitates with cubic crystal structure, at least in the beginning of precipitation, and the total Gibbs free energy of formation of AlN in the α-Fe matrix is analyzed.
