Notes:
Nickel powder was dry-milled using a high-energy disc-oscillating mill. The averageparticle size increases and the specific surface area diminishes with milling time. Crystallite sizedecreases and microstrains increase, under the same conditions, as shown by X-ray analysis. At120 min milling time, the crystallite size has a value of 17 nm, i.e., a nanostructured powder, with aperturbed lattice, is obtained. The above results have been compared with published data about theeffects of milling on a ceramic powder. There is, in both cases, a general agreement concerning thechanges produced in crystallite size. Nevertheless, opposite results are reached regarding particlesize and specific surface area
