Ultrasonic Crystallization of Monotectic Zn-2%Bi Alloy
In current studies, the authors examined the influence of ultrasonic vibrations on the solidification of Zn – Bi 2% alloy. The research reveals that ultrasonic vibrations have a sufficient influence on the crystallization process. In the case of both groups of ingots (Zn and Zn-2%Bi), the difference...

| description | In current studies, the authors examined the influence of ultrasonic vibrations on the solidification of Zn – Bi 2% alloy. The research reveals that ultrasonic vibrations have a sufficient influence on the crystallization process. In the case of both groups of ingots (Zn and Zn-2%Bi), the differences in microstructure and mechanical properties could be observed. The methodology was based on the casting of two samples from the same ingot form with identical configurations. One of the samples was used as the reference (cast without ultrasonic) and the other to examine ultrasonic vibrations' influence. Casting with ultrasonic vibration was carried out with a frequency of 35 kHz. Sonotrode was located on the underside of the designed crucible. The samples were circular shape with a diameter of 50 mm and a thickness of 10 mm. A tensile compression test, Vickers microhardness test and microscopy analysis were performed. The results showed enhanced organization of microstructure and the fragmentation of grains in the case of the ingots with the ultrasonic vibration presence. |
