Abstract
|
Corrosion
fatigue refers to the process in which a metal fractures prematurely under
condition of simultaneous corrosion and repeated cyclic loading. Tensile
residual stresses caused by certain manufacturing processes are the main causes
of decreased structural life of structures under cyclic loading and corrosive
environments.
Applying ultrasonic impact treatment is an effective method for enhancing fatigue behavior of materials. On the other hand, it has some positive effects on corrosion resistance of metals. Researchers studied the effect of ultrasonic impact treatment on corrosion fatigue behavior of A106-B welded steel pipe, provided by gas refinery. They found that enhanced corrosion fatigue life can be achieved by application of ultrasonic impact treatment. |
