The present review paper traces the development of nanocrystalline copper (Nc-Cu) and nanocrystalline nickel (Nc-Ni) and their mechanical properties. The objective is to summarise the various results available in the literature. The mechanical properties discussed are elastic modulus, Poisson's ratio, hardness, yield stress, ultimate tensile stress, strain/elongation to failure, superplasticity, creep, fatigue and fracture properties. The review is limited to bulk nanocrystalline materials. Shortcomings and limitations of the various studies that have been conducted are also highlighted. The present compilation is expected to be useful for researchers engaged in experimental work and computer modelling in this area.
