Abstract
An alloy of the chemical composition Ti-45Al-5V (at. %) was synthesized by mechanical alloying in a Szegvari-type attritor from elemental powders of high purity. The powders were further consolidated by hot isostatic pressing and hot isostatic extrusion. The resulting material was composed of a mixture of TiAl- and Ti3Al-based phases. However, no lamellar microstructure, typical of such alloys, was observed. The alloys exhibited exceptionally high yield strength, together with satisfactory ductility and fracture toughness. The high strength was unequivocally due to grain refinement and the presence of oxide dispersoid.
