In Situ TEM Nanomechanical Testing

  • Conference paper
MEMS and Nanotechnology, Volume 5

Abstract

Correlating the mechanical behavior of metals with the underlying defect mechanisms remains an outstanding challenge for the development of new material systems. In situ Transmission Electron Microscopy (TEM) nanomechanical testing provides an experimental technique whereby the behavior of defects such as dislocations and twins can be observed in real time while quantitatively correlating their behavior with an applied stress. This paper highlights recent experiments utilizing in situ TEM testing to investigate the behavior of twins and dislocations in FCC, BCC, and HCP materials. Examples of recently developed experimental approaches and future directions of in situ TEM nanomechanical testing are presented.
