Abstract

The intermetallic alloys Ti-15wt.%Al-7wt.%Cu, Ti-15wt.%Al-7wt.%Cu-10wt.%Nb and Ti-15wt.% Al-14wt.%Cu were vacuum arc melted followed by rapid solidification by the pendant drop melt extraction technique in vacuum. A detailed characterization of these rapidly solidified materials was conducted using light optical microscopy, scanning electron microscopy-energy dispersive spectroscopy, microhardness, bend ductility tests, scanning transmission electron microscopy, X-ray diffraction and differential thermal analysis. The presence of niobium improved chemical homogeneity of the copper and alluminum and refined the microstructure, resulting in improved ductility at room temperature.
