The grain boundary structure of the Ni{sub 3}(Fe,Cr) alloy is studied in states with a short and long-range order formed at the phase transition A1→L1{sub 2}. It is found that the new boundaries of general and special types are formed during an ordering annealing, wherein the special boundaries share increases. The spectrum of special boundaries is changed due to decreasing of ∑3 boundary share. It leads to weakening of the texture in the alloy with atomic long-range order. The features of change of the special boundaries spectrum at the phase transition A1→L1{sub 2} in the Ni{sub 3}(Fe,Cr) alloy are determined by decreasing of the stacking fault energy and the atomic mean square displacement at the chromium doping.
