Abstract
AbstractThe room temperature densities of Ni-Fe (0 to 70 wt.-%) have been determined by X-ray diffraction and hydrostatic weighing. Swedish charcoal iron (kindly supplied by the British Steel Corporation) with main impurities (wt.-%): Mn 0.15, Si 0.07, P 0.03, and C 0.03 and 99.999% pure nickel were melted, rolled and folded, and remelted, in an argonarc furnace with a Ti getter. The alloy compositions (calculated from the batch weights) are shown in Table I. Lattice parameters were obtained using Fe-filtered Co radiation on filings smaller than 150 mesh which had been annealed for 30 min at 800°C in an evacuated glass tube and then air cooled. The data were analysed by a Nelson–Riley plot. Good agreement was obtained with the lattice parameter data of Bradley et al. although in each case the present results were smaller. The greatest difference was 0.00049 nm which occurred with the pure Ni, but on the alloys the agreement was much closer. Densities calculated from the lattice parameters are shown in Tab...
