The influence of multiple solution annealing on kinetics of structural transformation of maraging steels

The paper presents effects of multiple solution-annealing on kinetics of structural transformation of maraging steels 18 9 5. Multiple solution-annealing testing was carried out in dilatometer by simultaneous registration of transformation temperatures austenite start As at heating and martensite start Ms at cooling and registration of linearly dilatatic changes. Analysis of dilatometric curves has quantified coefficients of dilatation during heating and coefficient of contraction during cooling, and has established mathematical model for determination of quantity of retained austenite in microstructure of maraging steels.
