Characteristic Features of Rolling Texture Development in FCC Alloys Having Very Low Stacking Fault Energies

Š110‹ symmetric tilt grain-boundary structures in fcc metals with low stacking-fault energies

Twenty-one ^110& symmetric tilt grain boundaries ~GB’s! are investigated with atomistic simulations, using an embedded-atom method ~EAM! potential for a low stacking-fault energy fcc metal. Lattice statics simulations with a large number of initial configurations are used to identify both the equilibrium and metastable structures at 0 K. The level of difficulty in finding the equilibrium struct...

Stacking Fault Energies of Tetrahedrally Coordinated Crystals

The energies of the intrinsic stacking fault in 20 tetrahedrally coordinated crystals, determined by electron microscopy from the widths of extended dislocations, range from a few mJ/m to 300 mJ/m. The reduced stacking fault energy (RSFE: stacking fault energy per bond perpendicular to the fault plane) has been found to have correlations with the effective charge, the charge redistribution inde...

Continuum understanding of twin formation near grain boundaries of FCC metals with low stacking fault energy

Deformation twinning from grain boundaries is often observed in face-centered cubic metals with low stacking fault energy. One of the possible factors that contribute to twinning origination from grain boundaries is the intergranular interactions during deformation. Nonetheless, the influence of mechanical interaction among grains on twin evolution has not been fully understood. In spite of ext...
