For the study of stress state and the level of heat treatment in engineering alloys, the thermo power (S) measurement is proposed as an acceptable method after a suitable calibration. In this paper, we focus on the determination of the influence of phase relations from the point of view of thermo power using industrial pearlitic carbon steels. The results of thermoelectric power measurements reported in this paper do confirm the applicability of S (T) measurements as non-destructive testing of quench hardening in pearlitic steels.
