| Abstract | ||
| The expansion in using Al-Si Alloys for the industrial and engineering applications for their distinguished properties, presented in the combination between mechanical properties and corrosion resistance in addition to the light weight, leads to find substitution resources to produce these alloys and more than 40% of the world production depends upon such a kind of production. Therefore, it is necessary and important to search in details the mechanical properties and microstructure of the recycled or secondary alloys. In this research , many types of practical experiments are made for the Al- Si alloys by adding recycled alloys in different percentages (25- 36%) , which produced by precision casting ,specimens prepared for the testing of tension , torsion, impact, fatigue and microstructure ,to find the optimum mechanical properties with different variables by preventing the defects produced by casting such as the presence of hydrogen and Al2O3 and their effect on the mechanical properties .It has been found the higher percentage of the original alloy improving the mechanical properties in the new alloy. | ||
