Abstract
AbstractAn attempt was made to change the crystal structure of the intermetallic compound Al3Ti from DO22 to Ll2, by replacing Ti with several alloying elements. The alloying elements chosen in this study were Sc, Er and Lu with which Al forms intermetallic compounds having LI, structure. Ingots weighing about 50g of Al3(Ti1-xMx) — M represents alloying element and the x value is 0, 0.25 or 0.5 — were melted in an argon plasma arc furnace. X-ray diffraction, energy dispersive spectroscopy and scanning electron and optical microscopy were carried out to examine the microstructurc in relation to the kind and amount of alloying elements. Microstructural observation revealed the occurrence of an Ll2 phase in all M bearing alloys. Compression tests were also carried out to assess the ductility of these alloys. The results showed that the Sc alloying is effective to increase the room temperature ductility of Al3Ti.
