Abstract: An addition of Ti as alloying element to Al-Si binary alloy will reduce the undercooling-abili- ty on rapid solidification of the melt-spun ribbon.The microstructure will be encoarsened even at initiation of its solidification,so as to aggravate the eellular segregation of Si in the alloy ribbon.

Key words: rapid solidification, Ti, Al-Si alloy, structure
