A deformation processed beta-Ti+Y metal-metal composite
A Ti-20V-20Y deformation processed metal-metal composite was deformed axisymmetrically by extrusion and swaging to a true strain of 5.9. Tensile strength, ductility, Y phase thickness and spacing, and preferred crystallographic orientation were examined at several levels of true strain as the deformation progressed. The Ti-V metastable BCC solid solution matrix developed a [10 (1) over bar0] fiber texture. The Y second phase developed a [110] fiber texture that constrained the Y phase to deform in plane strain. Relatively high tensile ductility was observed at all levels of deformation processing strain.
