Al based Sb - 42.4% Mg - 57.6% Al ternary eutectic alloy was melted by vacuum melting furnace, and was
casted into kokil mould. Then, in order to observe the effect of heat treatment, samples were investigated
as-cast and under heat-treated conditions. Designed samples were homogenized at 573 K for 1.5 h. The
values of enthalpy of fusion (H) and the specific heat capacity (Cp) of the solid phase for Al based the
ternary eutectic alloy were measured with DSC. The crystal structure parameters and the grain sizes for the
alloys were investigated by XRD diffraction. Mechanical properties of the ternary eutectic alloy were
studied with compression test. The effects of heat treatment on the microstructures and the microscopic
fracture surface morphology of the aged samples were examined by FESEM. The microhardness for the
alloys was measured from 5 different points with Vickers microhardness device. The compositions of the
ternary alloys were determined by Energy Dispersive X-Ray (EDX) analysis.
