Extra-electron induced covalent strengthening and generalization of intrinsic ductile-to-brittle criterion
Traditional strengthening ways, such as strain, precipitation, and solid-solution, come into effect by pinning the motion of dislocation. Here, through first-principles calculations we report on an extra-electron induced covalent strengthening mechanism, which alters chemical bonding upon the introd...
