Abstract Scope The precipitation evolution was studied during aging of 2.25Cr -1Mo steel at 550 °C. The as-received steel was aged in two different ways: the first one was the a continuous isothermal treatment at 550°C for times up to 2000 h and the second aging was performed using isothermal aging cycles which consisted of aging at 550°C for 60 min and then water quenched at room temperature. M23C6 and M6C precipitation occurred intragranular and intergranular in both types of aging. The coarsening of the carbides was observed to occur with the increase in aging time. Nevertheless, the growth kinetics coarsening was faster in the case of isothermal aging cycles. The hardness decreased with aging time in both cases; however, it occurred in a shorter aging time for the cyclic aging. Nanoindentation tests indicated the increase of ductility as the aging time increased.
