High Temperature Corrosion or Metallurgical Damage.
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
