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

Metals: grain neighbours influence twin formation during deformation Grains that should not favour twin formation exhibit twinning as a result of surrounding grains acting on their boundaries. A team led by HyoungSeop Kim at the Pohang University of Science and Technology in the Republic of Korea si...
