Abstract
The effects of coupling equal-channel angular pressing (ECAP) and heating at semisolid temperature on the microstructure of an Al-Fe-Si alloy were investigated. The microstructure of the equal-channel, angular-pressed samples after semisolid heating was found to be globular, fine, and uniform. Both the globularity and the grain size of the semisolid samples increased by increasing the holding temperature and holding time. The kinetics of grain coarsening was studied and the apparent activation energy was calculated on the basis of Lifshitz, Slyozov, and Wagner theory. Coupling ECAP and semisolid heating resulted in an enhanced microstructure and mechanical properties in the Al-Fe-Si alloy.
