TLDR
In this article, the precipitation kinetics of six alloys containing 1.00 −2.69 wt. % cobalt were determined at small departures from equilibrium and the results were interpreted in terms of classical nucleation theory and were consistent with the expectation of the chemical model.About:

The effect of volume fraction on particle coarsening: theoretical considerations
TL;DR: In this paper, the authors modified the theory of diffusion-controlled particle coarsening developed by Lifshitz and Slyozov and Wagner (LSW) to take into account the volume fraction, φ, of precipitate.

Crystal Nucleation in Liquids and Glasses
TL;DR: In this paper, the authors focus on measurements and theories pertaining to homogeneous nucleation under cooled liquids and glasses that transform to phases of the same composition, and incorporate time-dependent nucleation and the interface kinetics into the field-theoretic approaches to give theories that are as widely applicable and, hence, testable as the classical theory.

Nucleation in solids: The induction and steady state effects
TL;DR: In this article, the authors describe the process of nucleation, growth and coarsening, which combines to dictate the final particle density produced by a phase transformation, illustrated in Fig. 1, which depicts the number of particles vs. time.

The coarsening of γ' in Ni-Al alloys
Alan J. Ardell,R.B. Nicholson +1 more
TL;DR: In this paper, the coarsening behavior of the cube-shaped \ gg particles and the absence of large coherency strains in the Ni-Al matrix are the factors responsible for the excellent agreement between experiment and theory.

Homogeneous Second‐Phase Precipitation
TL;DR: In this paper, the authors defined a cluster-dynamics approach to generalized nucleation theory and compared it with the classical and non-classical nucleation models.

Diffraction contrast from spherically symmetrical coherency strains
Michael F. Ashby,L. M. Brown +1 more
TL;DR: In this article, the properties of images formed by diffraction contrast in thin metal foils viewed by transmission electron microscopy are studied by means of the dynamical theory of diffraction, including absorption.

TL;DR: In this paper, the velocities of 10-Mc/sec acoustic waves in copper single crystals in the range from 4.2\ifmmode^\circ\else\textdegree\fi{}K to 300\ifmode^''circ\circ''else\ text degree\fi {}K were determined.

Coherent fluctuations and nucleation in isotropic solids
TL;DR: In this article, a new free energy function for coherent nucleation in isotrpic solids was obtained by adding a suitably defined elastic energy term to the free energy, which has all the properties of a thermodynamic potential for coherent processes.

Diffusion of Iron, Cobalt, and Nickel in Single Crystals of Pure Copper
TL;DR: In this paper, the authors measured the diffusion of radioactive tracers of Fe, Co, and Ni in single crystals of pure copper and obtained the results as a function of temperature from about 700 to 1075 deg C. The experimental data yielded unexpectedly large diffusion coefficients at low temperatures in some cases and several possible causes are considered.

Ostwald ripening of precipitates in solid matrices
TL;DR: In this paper, it is shown that in the absence of dislocation loop emission, one of two kinds of coupling of diffusive fluxes occurs, as determined by the rate of entropy production, and the effective diffusivity is calculated for an interstitial solid solution (αFe-C), a coherent precipitate system (Cu-Co), and oxide-in-metal type of system.
