Abstract

Variation ofstructural parameters of phases in the mechanically alloyed system (Fe100-x-yCrxNiy)75C25as a function of the annealing temperature and chromium andnickel concentrations is considered. The data obtained earlier by X-raydiffraction are considered here in combination; it is shown thatlattice parameters of the cementite phase in different samples shouldbe compared for samples with the best conditions of cementitepreparation. The lattice parameters of the phases formed after mechanicalalloying differ from the reference values and approach them asthe annealing temperature grows. The lattice parameters of cementite resultedfrom annealing also vary depending on the doping element anddiffer from both reference cementite and undoped mechanically alloyed cementite,which is explained by the influence of chromium and nickelon the lattice.
