Abstract
The properties of the surface layer of a material are measured by a technique which employs the transmission of ultrasonic waves from varying angles of incidence into a specimen, from a transducer at a point spaced from the specimen. The backscattered waves are detected and evaluated from the varying angles to detect the local maximum intensity, from which the corresponding properties of the material are determined.
