Classifying internal defects in forgings based on flaw-detection patterns obtained by ultrasound

Metallurgist Aims and scope

Abstract

A method has been proposed for classifying internal defects in forgings based on the flaw-detection patterns obtained in ultrasonic testing. The reliability of the method is greater than 75%. Also, a program has been developed to classify internal defects in relation to their length and their location through the thickness and width of forgings. The method is valid for flaw-detection patterns in groups I and III. The method is now being used at the Chelyabinsk affiliate of the Ural Forging Company. The method of classification can also be used to identify internal defects in cylindrical specimens obtained by free forging on presses.
