Abstract
Acoustic energy is introduced into small melts of solidifying aluminum alloys using a metal probe vibrating at 8 kc per sec. Several changes caused by this treatment are observed in the solidified ingots. These include size reduction of inter-metallic crystals, a decreased gravity segregation of these crystals, grain refinement, and porosity reduction. No large increases of tensile strength are observed. The power radiated into the melt is estimated by a calorimetric method. It is shown that a cavitation mechanism is in qualitative agreement with the observations.
