Abstract

The strength of electrodeposited nanocrystalline Ni increased rather than decreased after annealing for 1 h at temperatures below 150°C, with little change in the grain sizes or detectable impurity segregation. Annealing at 200°C can be utilized to tailor the grain size distribution for improved ductility in combination with good strength. Further annealing at above 250°C, however, induced a transition to brittle behavior due to impurity segregation to grain boundaries concurrent with grain growth. © 2004 Acta Materialia Inc.
