Interesting studies devoted to the influence of Sm on the microstructure and corrosion resistance of AZ91 magnesium alloy treated by ultrasonic vibration are presented in the article. But there are a nuer of comments and recommendations. 1. A very short
Authors tried to braze magnesium alloy in air using no flux with the aid of ultrasonic vibration, and investigated the effect of brazing conditions on the joint properties. The main results obtained in this study are as follows.
Applying ultrasonic vibration made it possible to braze the magnesium alloy in air without flux and the joint strength was so high that the joint fractured
Ultrasonic C-scan experiments are conducted to quantitatively evaluate artificial discontinuities in magnesium alloy missile cartridges. The experimental results show that the amplitude of the ultrasonic signal after path compensation can be increased by 6%, and the relative errors between the measured value and the theoretical value of the discontinuity size are no more than 5%.
