Abstract
The precipitation evolution was studied experimentally and numerically during aging of as-cast heat resistant steel at 700, 800 and 900 °C. Thermo-Calc result showed a good assessment of the non-equilibrium phases for as-cast HK40 steels in comparison to the experimental results. In contrast, the Time-Temperature-Precipitation diagram for the M23C6 precipitation calculated with PRISMA showed a good agreement with the experimental growth kinetics precipitation for the steel after aging at 700, 800 and 900 °C.
