APPLICATION OF THE METHODS FOR PROCESSING SIGNALS FROM ULTRASONIC SURFACE WAVES DURING THE STUDY OF INDUCTION-TEMPERED MATERIALS

摘要：

The paper presents results of the study of induction-tempered materials by means of ultrasonic surface waves. It comprises analysis of material mechanical properties, measurement of the velocity of ultrasonic surface waves and processing of ultrasonic wave signals (spectral and cross-spectrum analysis). The approach can be used for the identification and assessment of layered materials.
