Abstract

In this research study, the influence of nanocrystalline surface modification on microhardness, tensile response and fracture behaviour of an oxide dispersion strengthened copper-niobium (Cu-Nb) micro-composite was investigated. The presence of a hardened surface layer and associated compressive residual stress lead to a noticeable increase in micro-hardness and a marginal improvement in both stiffness and strength. The increase in work hardening is quantified by the monotonic stress versus strain curve. For both the as-provided and surface treated composites tensile fracture was macroscopically ductile and microscopically revealed features reminiscent of locally brittle and ductile failure mechanisms. The mechanical properties and fracture behaviour is discussed considering nature of loading and intrinsic microstructural effects.
