Using a phase field model, we have investigated the role of plasticity on the morphological evolution of a precipitate during its diffusion-controlled dissolution, when submitted to shear loading. It is shown that the plastic strain pattern in the ma

Zn-Al-Mg coatings are characterized by a complex microstructure with dendritic and eutectic phases. This heterogeneous phase distribution contributes to multiple deformation and damage mechanisms. The presence of brittle phases promotes crack initiat

Complex microstructure evolution has been observed \rev{both bare and coated } Ni-based single crystal superalloys. Rafting and $\gamma'$ depletion are investigated in this study through a brief experimental analysis and a detailed phase field model

The present work demonstrates that the pencil glide mechanism is a physically reliable and a computationally efficient model to simulate the nonlinear behaviour of b.c.c. single and polycrystals. For that purpose, the pencil glide extension of Schmid

Rapid solidification leads to unique microstructural features, where a less studied topic is the formation of various crystalline defects, including high dislocation densities, as well as gradients and splitting of the crystalline orientation. As the

The microstructure evolution due to thermomechanical treatment of metals can largely be described by viscoplastic deformation, nucleation and grain growth. These processes take place over different length and time scales which present significant cha
