AB  - Al-Sc alloys are usedin the industry due to the various properties. There is an interest ofresearcher for theoretical and experimental study for this alloy. TheImportance of this alloy is that the effect of small concentration addition ofScandium has a great effect on the chemical and physical properties of alloys.In this study Al-1,1Sc and Al-1,9Sc alloys are studied experimentally andtheoretically. Produced alloys are investigated by XRD analysis that resultsshowed that the alloys have fcc crystal structure. The experimental results areused to calculate many elastic properties of the alloys by a software (EMTO).By using the experimental data, peak wideness, crystal size, dislocationdensity, Young’s constant and maximum stresses on (hkl) layers are determinedand discussed. According to the results of this study, it is observed that theparameters depend on the related crystal layers and Al-1,1Sc alloy has bettermechanical properties than Al-1,9Sc alloy.
