Microstructure and mechanical properties of ZA27 alloy matrix composites
Abstract
ddThe effect of Al2O3 and SiC particles on microstructure and strength (compression) of ZA27 (zinc-based alloy) was studied. Two composites were produced by compocasting process, i.e. particles of strengtheners were continuously added to the semi-solid melt which was vigorously stirred. The concentration and size of strengtheners were approximately the same, i.e. 3wt.% and 15 mum, respectively. Comparative investigations of microstructure (optical and scanning electron microscope) and compression strength (from room temperature to 170 degreesC) of composites and the corresponding as-cast alloy, produced by standard melting and casting process, were carried out. The dendritic structure was nearly completely removed by compocasting process, whereas a rather inhomogeneous distribution of strengtheners (particularly Al2O3) in the matrix was achieved. The strength of both composites was superior to that of as-cast alloy, the difference being greater with increase in temperature. The effect ...of Al2O3 and SiC particles on matrix strengthening was approximately the same.
