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
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%.
Investigations into the effects of magnesium content and cooling rates on the mechanical properties of aluminium-magnesium alloys refined with titanium-boride master alloy was conducted. Experimental samples were produced from melt with Mg content ranging from 0% to …
Especially when welding parts size shape is not so good, be welding parts of the natural vibration in the weld seams or basal material will produce crack. From the principle of ultrasonic welding speaking, the quality of the surface to the joint formation of tribological properties and physical metallurgical process, therefore, we must pay special attention to welding surface very good treatment.

Ultrasonic spray nozzles can produce typically smaller particles sizes than conventional spray nozzles, thus ultrasonic generated droplets can more efficiently be dried in flight. Additionally the low velocity of the spray generated increases nanoparticle yields, keeping material aloft longer and less coating of the chaer walls of a spray dryer when compared to conventional methods.
