Abstract

Al-Sc alloys are used
in the industry due to the various properties. There is an interest of
researcher for theoretical and experimental study for this alloy. The
Importance of this alloy is that the effect of small concentration addition of
Scandium 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 and
theoretically. Produced alloys are investigated by XRD analysis that results
showed that the alloys have fcc crystal structure. The experimental results are
used to calculate many elastic properties of the alloys by a software (EMTO).
By using the experimental data, peak wideness, crystal size, dislocation
density, Young’s constant and maximum stresses on (hkl) layers are determined
and discussed. According to the results of this study, it is observed that the
parameters depend on the related crystal layers and Al-1,1Sc alloy has better
mechanical properties than Al-1,9Sc alloy.
