Study of Al11Ce3 distribution in aluminum matrix produced via centrifugal casting Conference Poster uri icon


  • This research studied the distribution of the Al11Ce3 intermetallic phase in a centrifuged specimen as function of the rotational speed, which affects the solidification time. To comprehend the temperature distribution upon casting, the centrifugal caster was outfitted with a thermocouple embedded in the mold. As expected, cast specimens presented a notable phase concentration gradient, with higher volume content in the external zone of the casting. The cylindrical samples were analyzed along the main axis (centrifugal force direction) using microscopy and microhardness tests. Our results show how composition, cooling rate, and rotational speed were critical for the growth and segregation of Al11Ce3.
