摘要：Face-centered cubic (fcc) metals exhibit outstanding mechanical properties both in small-sized and bulk nanostructures and are thus promising for applications in micro/nano electromechanical systems (M/NEMS). Uncovering the intrinsic deformation mechanisms of small-sized metals is of critical importance for evaluating their feasibility in M/NEMS applications. Recent advances in in situ transmission electron microscopy (TEM)–based mechanical testing techniques open up opportunities for achieving a mechanistic understanding of the atomic-scale deformation mechanisms. This article reviews recent progresses in in situ TEM studies on the various plastic deformation modes of small-sized fcc metals, including dislocation slip and twinning, phase transformation–mediated plasticity, reversible structure formation, diffusion-mediated plasticity, and void-assisted plasticity and fracture. Promising directions for future in situ TEM investigations on fcc metals are also enumerated.
