Abstract

The isothermal precipitation kinetics of Nb(C,N) in strained austenite of a Nb-microalloyed steel was quantitatively investigated using electrical resistivity (ER) and interrupted compression methods and validated with transmission electron microscopy (TEM). The difference in precipitation start time (P_s) between the two methods is too small to compare the accuracy of the methods. The precipitation finish time (P_f) exhibits the larger difference between the two methods. The interrupted compression method gives too early P_f because of particle growth with holding time.
