Analysis of the results of investigation of the kinetics of ordering in alloys of different systems by the methods of formal chemical kinetics

Several different alloy systems are used as examples to show that the experimental dependences of the degree of long-range order on the time of isothermal annealing can be approximated by the equations of formal chemical kinetics. It was found that there are functions-linear for actual processes-which can conditionally be used as a criterion of the accuracy of models of processes. The results obtained regarding the kinetics of the alloy Ni₂Cr are compared with calculations based on an ordering model in terms of the theory of absolute reaction rates.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 6, pp. 55–60, June, 1988.
