Research on Isothermal Phase Transformation Kinetics of TC21 Alloy

Abstract:

The kinetics of the martensite decomposition in TC21 alloy under isothermal conditions has been studied using dilatometry technique. The typical morphologies of decomposition products were also directly observed. At 500°C and 550°C, the mechanism of martensite decomposition occur by, at temperature between 600°C and 750°C, the martensite decompose by . up 800°C, the martensite directly transform to α and β phase. Time–temperature–transformation diagram with iso-lines tracing the amount of the martensite decomposition have been established.
