Resumen:
In the present work, zinc - aluminum alloys with reinforcing particles of silicon carbide were solidified and analyzed. The analyses were done performing hardness test (HV), quantitative metallography, and dimensional stability tests. Composition analysis of the different alloying elements along the cast samples were done by SEM (Scanning Electron Microscopy) and EDXA (Energy Dispersive X-Ray Microanalysis). Several correlations between properties, structures and compositions were found, showing the increase in hardness with the increase in the volume fraction of SiC particles. The alloys tested for dimensional stability during 1000 hr at 165 ± 2,5 °C were very stable.
