Abstract

Microstructural investigation of a deformed Ti~66.1~Cu~8~Ni~4.8~Sn~7.2~Nb~13.9~ nanostructure‐dendrite composite using transmission electron microscopy (TEM) reveals heterogeneous propagation and interaction of the shear bands, depending on the geometry of the interfaces between the nanostructured matrix and dendrites. The geometrical effect on the propagation and interaction of the shear bands is presented by the different morphology of the interfaces i.e. stepped and smooth interfaces suggesting a different amount of accumulated shear strains at the interfaces between the nanostructured matrix and the dendrites.
