| 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. ARB Cu/Nb is known to have high strength, thermal stability, and radiation damage resistance enabled by interface structures that are strong dislocation traps and good point defect sinks. Past work on this topic has linked certain processing pathways to preferred crystallographic textures and to specific interfacial characters; annealing can sharpen existing textures in ARB composites, and changes in rolling direction can access transient textures. We present texture data taken 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. The current work will be discussed in terms of crystallographic stability under strain path changes, as well as the link between processing and material microstructure. |
