Abstract

The effects of Fe addition and initial powder size distribution on mechanical properties of Al-20Si-3Cu-lMg alloy, prepared by gas atomization and followed by hot consolidation, were studied by using optical microscopy, transmission electron microscopy, X-ray diffractometry, tensile and wear test. The Al-20Si-xFe-3Cu-lMg (x=0, 5) alloys showed homogeneous and refined microstructure. Addition of Cu and Mg to Al-20Si alloy showed increased tensile property due to precipitation hardening. Addition of Fe to Al-20Si-3Cu-lMg increased tensile strength further due to the formation of spherical Al-Si-Fe compound during hot consolidation and phase transformed from the metastable phase. Alloy bars prepared from powder with wide-size distribution showed low tensile strength and wear resistance.
