چکیده:

This paper deals with the applicability of eddy current testing (ECT) technique to assess and quantify sensitization and intergranular corrosion (IGC) in thermally aged AISI type 316 stainless -steel.Chemical and electrochemical tests specified by ASTM A 262 Practices A and E (Strauss test) andGI08, and ECI’, were used to quantify degree of sensitization (DOS). The DOS was categorized based on severity of the crack after bend test in increasing order as W18ffected, fissured, cracked, andbroken. The eddy current (EC) amplitude increased with increasing DOS in both the as-aged andStrauss tested conditions. The EC amplitude in as-aged condition was smaller than in Strauss tested condition. Empirical relationships were established between ECf amplitude and other DOS parameters
