Abstract:

Microstructure of Ti-48 at. \% Al-1 at. \% V samples prepared by pulsed volume pressing by various regimes such as casting into copper or steel molds using additional gas pressure and casting into a steel mold without pressure was studied by X-ray diffraction, transmission electron microscopy, and optical microscopy. Neither texture typical of deformed alloys nor dendritic structure typical of cast TiAl alloys were found in the Ti-48 at. \% Al-l at. \% V alloy prepared by the method used. It was found that a high-strength state of the Ti-48 at. \% AI-l at. Clr V alloy cast in the copper mold under gas pressure can he provided by a specific combination of structure characteristics. This alloy consists of two ordered phases such as TiAl (gamma) having an L1(0)-type structure and Ti3Al (alpha (2)) having a D0(19)-type structure. The alloy has a polycrystalline structure close to the oriented lamellar one. The high yield strength of the alloy prepared by the method used displays the presence of a rigid deformation mode. The alloy structure is characterized by uniform equiaxed grains consisting of gamma and alpha (2) lamellae of certain orientations. The average grain size is approximate to 40 mum. The alpha (2) lamellae are nan ow (0.02-0.06 mum) and uniformly distributed.
