The effects of strain on the corrosion behaviour of X80 steel in 0.62 M NaCl aqueous solution were investigated in the present paper. An increase in strain causes the corrosion resistance of the specimen to present a down and up trend, with the lowest point at about 1.0 x 10(-3). When the strain increases further, corrosion resistance decreases again until the strain reaches 5.5 x 10(-3). After that, corrosion resistance improves with the increase in strain and tends to be relatively stable. The variation of corrosion resistance has much to do with the surface activity and behaviour of dislocation on the surface of the specimen. (C) 2011 Elsevier Ltd. All rights reserved.
