There are various types of metallurgical damages which are associated with the operation at high temperature in aggressive environment. Almost all of the metallurgical degradations take place progressively depending upon operating temperature, length of exposure, and metallurgy of exposed metal. Unless the damaging environment is not restricted in one area, the damage in all of the metallurgical degradations is usually wide spread over large areas. Most of the damages can be predicted with timely inspection using appropriate inspection techniques like eddy currents, back scattered ultrasonic spectroscopy, and metallographic replicas. Out of all the inspection techniques the metallurgical replica is the most reliable … Read more
Stress Corrosion Cracking also known as Environmental Cracking. It is a group of damage mechanisms in which cracks are initiated and propagate under the simultaneous effect of a tensile stress and corrosion due to environment. Stress Corrosion Cracking Explanation. The tensile stresses originate from processes like cold forming, welding, heat treatment, machining and grinding, while corrosive environment is introduced by various process conditions. Because most of the surface of affected material remains un‐attacked, it is very difficult to detect or predict the failure. Fine cracks develop and penetrating into the material at accelerated rate. These cracks … Read more
