Abstract Strain induced precipitation of complex carbonitrides in two microalloyed steels (Nb–V and Ti–V) has been studied using a stress relaxation technique. The results confirm the faster kinetics of precipitation in the case of Nb–V steel. The thermodynamic software Thermo-calc ™ has been used to determine the composition gradient of equilibrium precipitates for the two steels.
