The ultrasonic attenuation study for dislocation, grainboundary and precipitates morphologies of pure aluminum and Al-Mg-Si alloy.
碩士 === 國立中央大學 === 機械工程研究所 === 99 === The study used ultrasonic testing to obtain the attenuation of 99.999% pure aluminum and 6063 aluminum alloy. As the result, the measured attenuation is sensitively in varied dislocation density or dislocation loop, so that would increase the calculation errors....
