Deformation mechanism in high strength Cu/Nb nanocomposites

Deformation mechanism in high strength Cu/Nb nanocomposites have been investigated through in situ TEM observations in tension. The results explain the particular interface microstructure that was previously observed by high resolution TEM. Moreover, the observed loops mechanism could be modeled, and the simulation of the very high mechanical properties of this type of composites is in good agreement with experimental data. Some criteria for higher strength composites are proposed.
