The use of vibration casting of aluminum cast alloys in the process of solidification in metal form

Study of the mechanical properties of aluminum casting 356 alloy revealed that the alloys subjected to 100 Hz and 150 Hz vibration treatment showed the highest properties, as the tensile and the yield strengths improved by 20% and 10% respectively. The densities of the alloys subjected to the vibration treatment varied in the range of 2, 5–3, 7% as a result of the presence of segregation areas in the obtained cast ingots. The microstructural studies followed by an image analysis evaluated that the alloys subjected to the vibration treatment showed the refi nement of α-Al grains with an increase in the Si network area around them.
