X-Ray Computed Tomography for Failure Analysis Investigations
Abstract
Failure analysis is an important engineering evaluation in any product development cycle; essential to product reliability and evolution. The volumetric feature detection and three-dimensional positioning capability of X- ray computed tomography are valuable and cost saving assets to a failure analysis laboratory. Savings are realized in reduced risk, determination of proper direction for irreversible failure analysis activities and schedule improvement. Savings are realized in reduced risk, determining proper direction for irreversible failure analysis activities and schedule improvement. Failure analysis laboratories of sufficient size can justify the cost saving benefits of using CT for equipment procurement. Case studies of failure analyses have been demonstrated to the Air Force and industry showing the ability of CT to significantly benefit such studies. In some cases, CT can directly resolve the problem, and in other cases, provides key supplemental information for guiding further investigations and reducing the risk of incorrect or incomplete analysis. Examples have included mechanical and electrical system assembly, system internal measurements and fitups, and material damage evaluation. CT also can be applied to systems to observe the internal positions as a function of test conditions. High resolution (>4 lp/mm) CT with combined radioscopy (real- time radiography) capability is advocated for failure analysis facilities....
