%X The phases obtained in copper aluminium bronze alloy (Cu-Al10-Fe2) cast into a permanent die were investigated. The parameters examined were the pre-heating temperatures of the die and the graphite coating thickness. The phases ¦Á and ¦Ã2 were detected as well as the metastable phases ¦Â' and ¦Ã'. The intermetallics of the system Fe-Al were obtained in various stoichiometric compositions. The different cooling rates of the casting resulted in two mechanisms of transformation to ¦Á grains out of the unstable ¦Â phase, one being nucleation and growth producing needle shaped ¦Á grains, the other exhibiting a massive transformation to spherical ¦Á grains. These two mechanisms determine the changes in the size of the ¦Á grains as a result of changes in the cooling rate in its various ranges.
