Observations of low-temperature superplasticity in electrodeposited ultrafine grained nickel

In this study, superplasticity was obtained from electrodeposited nanocrystalline nickel at 350 degrees C, which is 0.36 of the melting point T(m). A maximum elongation of 895% was obtained at 0.4 T(m), which is a large reduction in temperature and increase in elongation over the previously reported best result for nickel.
