ABSTRACT

Аn improved ultrasonic method for non-destructive testing of materials is proposed in the paper. Тhe method is capable of determining material structure and mechanical properties, whereas subsequent measuring devices are designed. Moreover, the method is tested by studying the structure and physico-mechanical properties of specimens and products made of steel, cast iron and aluminum alloys. A correlation between the ultrasonic velocity and attenuation is found, on one hand, and material structure, strength and elastic characteristics are analyzed, on the other hand.
