| Abstract Scope |
Multilayered metals are a promising class of materials with outstanding strength, thermal stability, and irradiation resistance. Accumulative roll bonding (ARB) is the primary method for the synthesis of multilayered metals in bulk form for structural applications. Cu-Nb is among the most widely studied systems for understanding the structure-property relationships in ARB-produced multilayers. However, there has been no systematic work characterizing the wear performance of Cu-Nb multilayers. In this work, we microscratch tested multilayered Cu-Nb to understand the mechanical response under sliding wear. Cu-Nb laminates with layer thicknesses down to submicron scale have been produced by ARB. SEM, XRD, and microhardness measurements characterized the microstructure and mechanical properties. Microscratch testing and analyses of the wear tracks showed that the wear resistance dramatically increases as the layer thickness goes down to the submicron level. The findings provide key information towards the use of nanolayered metallic alloys in applications involving sliding contact conditions. |
