Microstructural and chemical characterization of Al3Ti alloy obtained with a rapid solidification technique

Different alloys of Ti-Al have been prepared using an are furnace under inert atmosphere. The liquid melt has been cast with a rapid solidification technique. The main purpose of this investigation is to explore the intermetallic phases obtained under this casting process and also the structural relationships between all the phases obtained in these types of alloys. The structural characterization of the specimens has been carried out using X-ray diffraction techniques. Chemical and morphological characteristics have been obtained using an analytical scanning electron microscope. Finally, some structural characteristics of the alloys have been obtained using an analytical transmission electron microscope. (C) 1998 Elsevier Science S,A. All rights reserved.
