Microstructure of a rapidly solidified Ti73Fe27 melt-spun ribbon

摘要

A Ti73Fe27 alloy was rapidly solidified bythe melt-spinning technique. Three microstructuresare found in the melt-spun ribbon of the alloy. Thefirst contains small TiFe particles in a β-Ti matrix,the second is a cellular microstructure composed ofβ-Ti and TiFe, and the third is eutectic of thesephases. The correlation between varioussolidification and cooling rates through the ribbonthickness to the three microstructures is explained.
