TL;DR: In this paper, a dislocation-based crystal plasticity model is employed to predict the heterogeneous distribution of stress, strain and dislocation activity and is coupled to a phase field model for the description of the nucleation, propagation, and growth of { 1 ¯ 012 } tensile twins.

TL;DR: In this paper, a crystal plasticity-based phase field model for twinning is employed to study the strengthening mechanisms resulting from the interaction between twin growth and precipitates, and the results indicate that the effective critical resolved shear stress (CRSS) for twin growth increases linearly with precipitate volume fraction and aspect ratio.

TL;DR: In this paper , the influence of scrap-related impurities on the thermodynamics and kinetics of precipitation reactions and their mechanical and electrochemical effects; impurity effects on precipitation-free zones around grain boundaries; their effects on casting microstructures; and the possibilities presented by adjusting processing parameters and the associated mechanical, functional and chemical properties.

TL;DR: In this article, the influence of grain boundary microchemistry and precipitation behavior in high-strength Al-Zn-Mg-Cu alloys has been investigated in a phase-field framework to simulate the complex kinetics of the non-equilibrium GB microstructures that develop in these important commercial alloys during heat treatment.
