EFFECTS OF INCLUSIONS ON THE MECHANICAL PROPERTIES OF ALUMINIUM
Öz
In this study, effects of inclusions on the mechanical properties of pure aluminum
were investigated. Special attention had been paid to inclusion chemistry, size
distribution and volume fraction. Silica (SiO2) and alumina (Al2O3) particles of
(-63+53)µm and (-45)µm size ranges had been added to liquid aluminum in 1% and
5% volume fractions. Casting had been done in a metallic mould to produce 20 rods,
10mm in diameter and 80mm in length. Tensile and fatigue specimens had been
prepared from these rods and tests had been done at room temperature. According to
the results, tensile and fatigue strengths were reduced, as inclusion content was
increased. Inclusion size had a similar effect while inclusion chemistry did not
change mechanical properties. In the worst condition; larger size and 5% volume
fraction, fatigue strength, tensile strength and ductility had been reduced by 22%,
10% and 37% successively
