Abstract

The microstructural characteristics and mechanical property of the Nanocrystalline Nickel (No-Nickel), produced by Electrodeposition (ED) and Mechanical milling (MM), were investigated in the present work. From the nanoindentation study, we observed that MM-Nc-Ni showed lower hardness than ED-Nc-Ni and Microcrystalline (Mc)-Ni. ED-Nc-Ni showed a significant improvement in hardness. All the Nc-Nickel samples, regardless of processing methods and grain sizes, showed comparable elastic moduli. The lower hardness of MM-Nc-Ni is due to the presence of microcrystalline Nc-Ni.
