Effect of Shock Loading with Ultrasound on the Structure and Properties of the Metal of Welds and Products

Ultrasonic Treatment of the 304 Stainless Steel Melt

“…Osawa et al 12) applied ultrasonic treatment in the solidification of AZ91 alloy, as a result, fine and uniform microstructure was obtained, meanwhile, the yield strength and tensile strength were both improved significantly as well; Atamanenko et al 13) carried out experiments to investigate the process of aluminum melt treatment using ultrasound, and determined the effect of cooling temperature on the refinement of microstructure during solidification. However, the melt with high temperature would corrode the booster which plays a very important role in introducing ultrasound into molten metal, for this sake, the research of refining microstructure with ultrasound mainly focused on low-melting-point metal, [14][15][16][17][18][19][20] there is relatively less research about the effect of ultrasonic treatment on the highmelting-point metals, such as steels. Liu et al 21) treated T10 steel by using ultrasound introduced from the lateral, and studied the solidification microstructure, segregation, mechanical properties, and anticorrosion property under different powers.…”
