Superplastic materials exhibit very large elongations to failure,typically >500%, and this enables commercial forming of complex shaped components at slow strain rates of similar to 10(-4) s(-1). We report extraordinary record superplastic elongations to failure of up to 5300% at both high strain rates and low temperature in electrodeposited nanocrystalline Ni and some Ni alloys. Superplasticity is not related to the presence of sulfur or a low melting phase at grain boundaries. (C) 2010 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
