WebWhilst electron microscopy is therefore required to study the cavity nucleation stage, optical microscopy is normally adequate to follow the development of creep damage. Conventional NDT methods, e.g. magnetic particle inspection or ultrasonic inspection techniques, are not able to detect creep damage prior to the formation of a creep crack.
