The effect of ultrasonic melting processing on three-dimensional architecture of intermetallic phases and pores in two multicomponent cast Al-5.0Cu 0.6Mn-0.5 Fe alloys is characterized using conventional microscopy and synchrotron X-ray microtomography. (…) The results show that ultrasonic melt processing (USP) significantly reduce the volume fraction, grain size, interconnectivity, and equivalent diameter of the intermetallic phases in both alloys. The volume fraction of pores in both alloys is reduced due to the USP degassing effect. The refinement mechanism of USP induced fragmentation of primary and secondary dendrites via acoustic bubbles and acoustic streaming flow were discussed.
The 3D segmentation and volume rendering were performed using Avizo Lite v9.0.1. The 3D bilateral filter was applied to the raw images in order to increase the contrast and reduce noise.
