Intererystalline defects and some properties of electrodeposited nanocrystalline nickel and its alloys

Experimental results are presented concerning the influence of primary intercrystalline defects, i.e., grain boundaries and triple junctions, on the properties of nanocrystalline nickel and its alloys. The properties considered are largely based on nanostructured materials relatively free of secondary defects introduced during synthesis, such as porosity, residual amorphous regions, lattice dislocations and extrinsic grain boundary dislocations. These property studies include thermal stability and grain growth, mechanical, electrical, corrosion and hydrogen transport.
