ULTRASONICS AS A MEANS OF RATING STEEL CLEANLINESS

THE USE OF ULTRASONICS AS A MEANS OF RATING STEEL CLEANLINESS HAS BEEN INVESTIGATED. IT HOLDS CONSIDERABLE PROMISE IN INCLUSION DETECTION AND POSSESSES ADVANTAGES OVER CONVENTIONAL RATING METHODS SUCH AS METALLOGRAPHIC AND MAGNETIC PARTICLE. VARIOUS TYPES OF READOUT OF THE ULTRASONIC INFORMATION HAVE BEEN USED AND ONE APPEARS TO BE SUPERIOR TO THE OTHERS. FACTORS SUCH AS TEST FREQUENCY, SEARCH UNIT, SURFACE CONDITION AND DIRECTION OF SCANNING HAVE BEEN CONSIDERED. WORK HAS BEEN DONE WITH SEVERAL TYPES OF STEELS. ULTRASONIC RESULTS HAVE BEEN COMPARED WITH THE FATIGUE LIFE OF SPECIMENS TAKEN FROM THE VARIOUS BILLET SECTIONS AND A GOOD CORRELATION EXISTS. /AUTHOR/
