Abstract Scope |
ARB Cu/Nb nanolaminates have been studied extensively to link bulk processing parameters to changes in interface structure, microstructure, and extreme condition performance in layered heterophase composites. Nanoscale ARB Cu/Nb contains a high density of heterophase interfaces that mediate dislocation activity to make the composite many times stronger than its constituent phases. Past work on this topic has linked certain processing pathways to preferred crystallographic textures and associated interfacial character; annealing can sharpen existing textures in ARB composites, and changes in rolling direction can access transient textures. We present texture data measured via neutron diffraction from samples that have been annealed and subsequently subjected to different strain pathways to assess the degree to which we can sharpen and evolve textures in ARB composites. We then relate these processing-induced textures to mechanical behavior obtained from miniaturized tensile tests. |
