In July, the measurements of the treated discs texture using ultrasound sonotrode and generator, which took place during a visit to the company SonicArts in Warsaw. Discs were subjected to ultrasonic waves with an amplitude of several micrometers in 12 seconds while being boiled power on the device. Are on a single disc for the two reference alloys AZ31 and AZ91, and three discs for each of these alloys was sonicated successively in opiłkach iron placed in a container with water, the aqueous suspension of alumina and similar properties of the substance to the non-Newtonian liquid. Similar treatment was tape AZ91 alloy after extrusion side by Kobo and engine blade elements. Samples identified high stress state is treated with ultrasonic waves in a suspension of alumina for a period of 12 s with a power consumption 92 W. fragment pressed on the sleeve of the flange to the head without a proxy, as two pieces of tape from austenitic steel.
