Abstract
This research work focused on tensile, hardness, and influence properties of amorphous Al–Si-Mg cast alloys. Enhancement of aluminum alloy with Mg and Si was performed after which heat treatments were carried out on the produced samples. The result showed the percentage of Mg as 0.14, 4.14, 0.14, 0.32, and 0.20%, for as-cast aluminum, annealed, age-hardened, hardened, and glassy-phase samples, respectively. The percentages of Si were 2.01%, range of 1.94–4.10% and 3.37% for as-cast, heat-treated, and glassy-phase aluminum alloys, respectively. The impact tests showed an increase in impact value from 5.423 J of as-cast sample to 8.135 J of age-hardened sample. Hardened sample has the lowest impact value of 2.712 J while glassy-phase sample has the highest impact value of 10.847 J. The ultimate tensile strength of annealed sample is higher compared to as-cast while glassy-phase has the highest value. The SEM of the annealed alloy sample contains bright and dark regions indicating α and β phases, respectively.
