Abstract

A new method of ultrasonic featured-scan using power estimation based on ultrasonic scattering and absorbing was put forward. An experiment was conducted on a specimen made of silicon carbide particle reinforced aluminum matrix composites, from which the bottom echoes can hardly be acquired. The results show that the new method is effective to the testing of this kind of composites, which cannot be achieved by traditional ultrasonic C-scan and F-scan.
