Abstract

Compression and tensile testing of electrodeposited nickel films with micro-sized specimens were reviewed. Preparation of micro-specimens without the tapering was realized by the micro-specimen fabrication method developed in our group. Accurate micro-testing method with precisely-shaped specimens is needed to reveal micro-mechanical properties of electrodeposited metals. The micro-testing on nanocrystalline nickel plated by an electrodeposition method with supercritical carbon dioxide showed remarkably high strength, and the strength increased with a decrease in the specimen size. The results indicated grain boundary mediated deformation of the electrodeposited nanocrystalline nickel.
