NONDESTRUCTIVE TESTING - A SURVEY

BOTH STANDARD AND DEVELOPMENTAL METHODS FOR NONDESTRUCTIVE EVALUATION (NDE) ARE REVIEWED IN THIS SURVEY. THE HIGH RELIABILITY REQUIRED FOR AEROSPACE COMPONENTS HAS BEEN ONE FACTOR IN THE INCREASING DEVELOPMENT OF MORE EFFECTIVE METHODS, BUT MANY OTHER SECTORS OF INDUSTRY ARE MAKING USE OF THESE IMPROVEMENTS. MAJOR FIELDS OF NDE (THE USE OF LIQUID PENETRANTS, MAGNETIC PARTICLES, X-RAY RADIOGRAPHY, ULTRASONIC VIBRATIONS, AND EDDY CURRENTS) HAVE REACHED A HIGH STATE OF DEVELOPMENT. LESS WIDELY USED TECHNIQUES IN INDUSTRY INCLUDE STRAIN SENSING, NEUTRON RADIOGRAPHY LEAK DETECTION, HEAT (THERMAL OR INFRA-RED METHODS), AND THE USE OF MICROWAVES, ACOUSTIC EMISSION AND HOLOGRAPHY. THE INFORMATION IN THIS SURVEY IS BASED ON AN EXAMINATION OF PERTINENT LITERATURE FROM NASA AND ITS CONTRACTORS, AND DISCUSSIONS WITH SCIENTISTS IN THE FIELD. A COMPREHENSIVE REFERENCE AND BILIOGRAPHY WILL AID THE READER WHO SEEKS FURTHER DETAILS. /AUTHOR/
