Resumen o descripción
The effect of transition element addition and solution treatment time on the microstructure and hardness
of the Al-Si alloy were studied by Vickers microhardness, Rockwell B Hardness, X Ray Diffraction
(XRD), Optical Microscopy (OM) and Scanning Electron Microscopy (SEM). The A319 alloy and the
A319 alloys modified with Ni were solution treatment at 495 °C for 5 and 7h, quenching in water at 60
°C and aged at 170 °C for 0.5, 3, 5, 10 and 96 h. The Ni addition between 1 and 2 wt. % to the A319
alloy have a direct effect on the microstructure, the morphology, size and distribution of precipitates
during aging heat treatment, as well as, favors the formation of the Al-Fe-Ni, Al-Ni-Cu- and Al3Ni2
intermetallic phases, additionally, the Ni presence reduce the Cu content in the matrix for the Al2Cu
formation due formation of Al-Ni-Cu phases.
