Abstract

Thermoelectric power (TEP) measurements had been proved as an effective method for evaluating the metallurgical state of various alloys. The current work was conducted in order to evaluate the influence of the aging state of Maraging 250 steel on TEP values. Commercial Maraging 250 steel was aged at 500°C for 0.5-6 hours (hrs). TEP, hardness (Rc) and ultrasonic (US) measurements, were preformed on the as received and aged specimens. XRD measurements were used to identify the formation of precipitates (mainly Ni 3(Ti,Mo)), reverted austenite and to evaluate changes in the microstrain caused by the precipitation process. A correlation was found between the TEP and the various measurements as a function of the aging time.
