Abstract Scope One-dimensional carbon nanotubes (CNT), which are mechanically strong and flexible, enhance the strength of the host metal matrix. However, the underlying strengthening/fracturing mechanism at the nanoscale is not clear. Here, we report a numerical analysis of the strengthening mechanism of CNT in aluminum along with the in-situ experimental observation. Nanoscale plasticity and rupturing processes near CNTs were observed by in-situ mechanical tests inside a Transmission Electron Microscope (TEM). The fracturing entails notch evoluation, surface strain, atomic sliding, dislocation gliding/climbing and local shear response. The notch in nanoscale was pinned due to the high mechanical strength of CNT. Further molercular details of 1D nano-dispersion hardening due to CNTs will be discussed.
