The precipitation kinetics of NbC in ferrite matrix of a Nb microalloyed steel was investigated experimentally and numerically. The change in electrical resistivity due to NbC precipitation was measured at different constant temperatures as a function of holding time and was converted to the precipitation kinetics of NbC using a lever rule. The precipitation kinetics was compared with a classical nucleation and growth model and with the hardness. There is a good match among the calculated and measured precipitation kinetics of NbC and the hardness. The numerical and experimental results have been used to construct a precipitation-temperature-time diagram of NbC in ferrite matrix of the Nb microalloyed steel.
