Abstract

The phases obtained in copper aluminium bronze alloy (Cu-10wt.%Al-2wt.%Fe) cast into apermanent mould were investigated. The parameters examined were the thickness of thegraphite coating of the mould and its pre-heated temperature. The phases α andγ2 were detected as well as the metastable phases β′ and γ′. The intermetallics of the Fe-Al system were obtained in variousstoichiometric compositions. The different cooling rates of the casting led to twomechanisms of transformation into α-phase grains out of the unstable β-phase, one beingnucleation and growth producing needle-shaped grains, the other exhibiting a massivetransformation into spherical grains.
