The influence of size on the composition of nano-precipitates in coherent precipitation
Philosophical Magazine, 2014Various experiments show that the solute content in small coherent precipitates in their early stages of growth-coarsening is significantly lower than its equilibrium value and gradually increases with the particle size until equilibrium composition is reached.

Equilibrium shapes of coherent precipitates near a surface
Mechanics of Materials, 2018The shape stability of a two-dimensional precipitate embedded in a matrix has been theoretically investigated when it is strained due to an anisotropic lattice mismatch between the matrix and the precipitate. In the case of a semi-infinite matrix, the precipitate is found to align perpendicularly to the free-surface direction when both lattice ...

Coherent precipitation of M2C carbides in AF1410 steel
Materials Science and Engineering: A, 1989Abstract The effect of elastic coherency on the composition and stoichiometry of M 2 C carbide precipitates ( M ≡ Cr , Mo , Fe ) in AF1410 steel is analyzed utilizing thermodynamic conditions for mechanical, chemical and interfacial equilibrium between the ferrite (tempered martensite) and the M 2 C phase.

Calculation of TEM Contrast of Small Coherent Precipitates
Physica Status Solidi (a), 1989A new simple method to compute the image contrast of small coherent precipitates without strain contrast is proposed. The method is based on a perturbational expansion of the extra scattering due to the precipitate. Two approaches are possible – z-dependent and z-independent perturbation theory, which each have special advantages.
