Formatted Abstract/Summary
Quasi-directionally solidified plates were sand cast using unmodified Al-xSi-yCu-0.1Mg-0.5Fe alloy with two Si (x = 4.5 or 9 mass%) and three Cu (y = 0, 1 or 4mass%) contents, and the size of the intermetallic phase particles ( β-Al5FeSi and Al2Cu) assessed at constant secondary dendrite arm spacing (SDAS) using optical microscopy and back scattered electron images. Increasing the concentration of Si alone or in combination with Cu refined the β-Al5FeSi platelets, whereas increasing Cu at constant Si shows an SDAS and Si level dependent effect.
