Ultrasonic assessment of heat-damage in 7050 aluminum alloy
The effect of exposure of 7050 aluminum alloy to heat damage has been studied using ultrasonic techniques. Contact, immersion, and laser ultrasonic techniques were used. The relationships of ultrasonic attenuation with static material properties and material microstructure were evaluated. It was shown that attenuation measurements at high frequencies (>20 MHz) can provide an indication of material microstructure and thus mechanical properties of 7050 aluminum.
