Summary:The microstructure and mechanical properties of Ti–TiB based short-fiber composite materials manufactured by casting and subjected to deformation processing are investigated. Commercially pure VT1-0 titanium and two-phase VT8 alloys are used for matrix alloys. It is established that the short-fiber composite materials comprising about 10 vol.% of titanium monoboride can be successfully prepared by conventional casting. Regimes of deformation processing of the composite materials providing reorientation of titanium monoboride fibers with retention of a high length-to-diameter ratio are developed. The composite materials after deformation processing demonstrate higher strength characteristics and, as demonstrated for the VT8 based composite, high-temperature strength compared to the matrix material without a radical reduction of ductility.
