Evaluation of the EPR Technique for Measuring Sensitization in Type 304 Stainless Steel

Effect of Precipitation of σ-Phase and N Addition on the Mechanical Properties in 25Cr–7Ni–4Mo–2W Super Duplex Stainless Steel

“…In general, it was accepted that addition of the N moderate the precipitation while the precipitation and mismatch of the austenite phase were decreased for decreasing the impact value in the austenite stainless steel. 16,17) However, in this study the ferrite phase was depended on the higher than the austenite phase in Duplex Stainless Steel. Therefore, the amount of the Cr was decreased, which is due to increase the volume fraction of the austenite with added the N.…”

Magnetic and Electrochemical Techniques as Tools to Detect Deleterious Phases in Duplex Stainless Steels

“…The electrochemical potentiokinetic reactivation technique with double loop (DL-EPR), was first used to detect chromium carbides in austenitic stainless steels. [1][2][3][4][5][6][7][8][9][10][11][12] Later on, several groups adapted this technique to other materials and extended its scope of identification. [13][14][15][16][17][18][19][20][21][22][23][24][25][26] The use of the DL-EPR technique has been proposed for duplex stainless steels (DSS) to detect several phases, such as sigma, chi, and others.…”

Evaluation of the Susceptibility to Intergranular Corrosion for a Novel Cr-Mn-N Austenitic Stainless Steel Using DL-EPR

“…Several literatures [9][10][11][12][13] reported the use of DL-EPR test to study the sensitization and IGC behavior of AISI 304L SS and 316SS which contain nitrogen, but little literature is available on sensitization and IGC behavior of Cr-Mn-N austenitic stainless steels evaluated using DL-EPR. The present investigation established the relationship between sensitization temperature and DOS which confirmed by micro-morphologies.…”
