Abstract

The effect of thermal aging on microstructure and microhardness of as-cast Al-4Si-4Mg alloys has been studied. Al-4Si-4Mg alloys with 1 to 5 wt.% cerium addition were prepared using casting technique. Cast alloy were underwent heat treatment having a sequence of solutionizing, quenching and artificial aging. All the alloy were solutionized at 540 C for 4h followed by water quenching and age hardening 130 °C, 150 °C, 170 °C, 190 °C and 210 °C for 4, 3, 2 and 1 h. Detailed analysis of the microstructure was carried out using LEO Scanning Electron Microscope model 1450. Hardness was measured using Shimadzu Microhardness Tester (HMV-2000). Microstructure studied of alloy showed the cast dendritic structure is destroyed and the spheroidization of eutectic silicon after the heat treatment. The hardness was the highest after aging at 130 °C and 150 °C for 3 h, at 170 °C and 190 °C for 2 h and 210 °C for 1 h.
