Effect of Si content on the surface characteristics of aluminum alloy foil rapidly solidified by single roll method.

Rapidly solidified Al-Si alloy foils with Si content in the range of 0-20mass% were prepared by single roll method. Continuous and sound Al-Si foils were fabricated with Si content in the range of 0-16mass%. Dents on the roll contact side surface of foil disappeared when Si content became greater than 4mass%. Good surface characteristics of 99.99mass%
