Research Abstract |
Nickel thin films with the grain size ranging from sub-micrometers down to 10nm can be produced by changing the electrodeposition temperature and brightener contents. Free-standing thin films were produced by using polished stainless plate as cathode. The reduction of grain size is beneficial to fatigue crack initiation, while detrimental to fatigue crack propagation. In nanocrystals with the grain size less than 15nm, grain boundaries play a major role in fatigue micromechanisms.
