Ultrasonic reflection from simulated discontinuities and bottom surfaces were studied under water, as a fundamental experiment of ultrasonic techniques to be applied to the nondestructive testing of heavy steel forgings. Equivalent reflection surfaces of simulated discontinuities and of bottom were investigated and nomograms for the size of discontinuities were established from the ratio of flaw-to-bottom indications and the distances from transducer to the flaws. Although the results obtained may not be applied to heavy steel forgings as they are, yet they will be of some help for analyses of reflection phenomena in steels.
