Abstract

A single roller technique called melt overflow for direct casting metallic sheet, strip or foil is described. A simiple heat transfer nodel is developed to predict foil thickness frorn process parameters. The model agrees with thickness of Ti-6Al-4V cast strip. Cooling rates as high as 105 K/s are estimated from measuremnents of secondary dendrite arm spacings in 7075 aluminum alloys. Applications include magnesium-graphite composites.
