Abstract

The use of copper sheet precursor enhanced with niobium powder has been used to investigate similarities in properties to that of nano-laminar Cu-Nb sheets produced via Severe Plastic Deformation (SPD) with the process of Accumulated Roll Bonding (ARB). Previous experiments using the Accumulated Roll Bonding (ARB) to produce copper-niobium nano-laminar sheets have demonstrated its radiation damage tolerance, thermal stability, and spallation resistant properties. Characterization of niobium powder enhanced copper composite was done using optical microscopy, SEM, and Vickers micro-indentation. To have a comparison of the effects of using Nb powder on copper sheet precursor, Cu-Cu nano-laminar sheets were produced via ARB and were subject to the same conditions and characterizations. Results using micro-indentation have demonstrated a measurable increase in hardness and optical and SEM microscopy images have shown a difference in microstructure to that of pure ARB Cu-Cu.
