摘要: Abstract Research on the kinetics of precipitate formation and austenite reversion in maraging steels has received great attention due to their importance properties alloys. In present work, phase transformation an 18 wt.% Ni grade C250 was investigated using differential scanning calorimetry (DSC). Based calorimetric data obtained at different heating rates, modeled Johnson–Mehl–Avrami (JMA) theory. Good agreement between calculated transformed fraction experimental from DSC measurement is demonstrated for both transformations. The derived JMA kinetic parameters were then used simulate during isothermal ageing. Comparison literature carried out. Mechanisms discussed based value parameters.
