Abstract: Abstract We propose a two-mechanism theory to estimate the pinning effect of coherent precipitates on grain-boundary (GB) migration in grain growth, taking into account the important effect of elastic misfit strain at the coherent interface.… read more here.

Abstract: Abstract The 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… read more here.

DOI: 10.3390/ma18112436
Abstract: In this work, a crystal plasticity (CP)-based continuum modeling approach is employed to investigate the interaction between dislocations and coherent γ″ precipitates in the Inconel 718 (IN718) superalloy. A finite element (FE) model is developed… read more here.
