Effects of trapping dislocations within small crystals on their deformation behavior

KS Ng, AHW Ngan - Acta Materialia, 2009 - Elsevier
Micron-sized metallic crystals are much stronger than their bulk counterparts. However, their
deformation is jerky and they do not strain harden continuously, so that precise metal …
