Cryogenic (NDT) - Transition Detection/Phase Transformation

It is well known that the amount of residual stress in a material can be impacted by improper heat treating or manufacturing methods and is often a source of early fatigue life or altered mechanical behavior of metals. Completed phase transformation of metallic materials is critical to a specific materials structural integrity and can significantly contribute to the reduction of residual stress retained in a material and improved mechanical behavior. In order to remove residual stress in a carbon-metal alloy it is necessary to insure that a complete phase transition has occurred to a stable crystalline structure and then treated to remove the residual stress. Patented Cryogenic (NDT) and Cryogenic Transition Detection Processes can provide significant advancements in the review of these changes and transformations that often occur in different manufacturing processes.
