This paper reports the experimental findings on the
development of the premixed elemental Al5Cu and Al5Cu0.5Mg powder metallurgy alloys. Aluminum
powder was mixed with copper and magnesium powders in a macro- and a micro-level in order to
produce light and strong Al-based powder metallurgy alloys using standard powder metallurgy
processes. Differential thermal analysis of the powder mixtures was useful in determining
effective sintering regimes. The effects of processing parameters for sintering over
microstructure and product properties were highlighted. High strength Al-based powder metallurgy
alloys were developed with good microstructure from the premixed elemental Al5Cu and Al5Cu0.5Mg
compositions. It was shown that, using powder metallurgy production route with a micro-alloying
technique, the transverse rupture strength value after sintering of the base Al powder could be
increased 5 times from 84 MPa to 466 MPa. (C) 2011 Elsevier Inc. All rights reserved.
