Description

technical field [0001] The invention belongs to the field of measurement technology, and in particular relates to a detection device and method for a dynamic solidification sound field of metal materials under vibration conditions. Background technique [0002] Vibration solidification is to apply vibration to the molten metal in the solidification process, so that the crystal structure of the casting is refined due to the vibration, the residual stress of the casting is reduced and homogenized, and the mechanical properties are improved; the application of vibration in the field of metal solidification has aroused widespread interest. Pay attention to. Sokolov was the first to use a high-frequency device in 1935 to apply vibrations to the solidification process of pure metals. During the same period, Loomis et al. studied the law of applying ultrasonic vibration during the solidification process of metals and organic matter, and Eskin et al. explored the law of metal solid...
