| Nanocrystalline Ni-Fe alloys with composition in the 5wt% to 50 wt% Fe range were fabricated via the electrodeposition method. Very fine grain size (»approx. 11nm) with nearly random crystallographic orientation was obtained in alloys with equal or more than 15wt% Fe. For a nominally constant grain size, the hardness of the deposits decreased and the level of internal stresses increased with raising the iron content above 15wt%. At low iron concentrations, the deposit showed large grain size with a strong <100> texture. These observations are discussed in terms of the development of the structure during the deposition process. |
