Abstract
Evidence has been presented for the occurrence of twinned dendrites in rapidly solidified aluminum alloys containing nickel, platinum and zinc. Their existence offers an alternate explanation for the characteristic elongated parallel grain morphology in liquid quenched aluminum alloys. It is argued that twinned dendrites can be stabilised even at high growth rates by a non-equilibrium solute trapping.
