摘要： The invention relates to the pressure processing of metals, and specifically to methods for preparing rods and workpieces from titanium alloys, with applications as a structural material in nuclear reactor cores, in the chemical and petrochemical industries, and in medicine. The invention solves the problem of producing rods from high-quality titanium alloys while simultaneously ensuring the high efficiency of the process. In order to achieve same, a method for preparing rods or workpieces from titanium alloys includes the hot forging of an initial workpiece and subsequent hot deformation, the hot forging of an ingot is carried out following heating to a temperature within the range (Temperature of polymorphic transformation (Tpt)+20)°C to (Tpt+150)°C with shear deformations primarily in the longitudinal direction and a reduction ratio of k = (1.2-2.5), and then performing hot rolling forging, without cooling, within a temperature range of (Tpt+20)°C to (Tpt+150)°C, changing the direction of shear deformations to being primarily transverse and with a reduction ratio of up to 7.0, and conducting subsequent hot deformation by heating deformed workpieces to within a temperature range of (Tpt-70) to (Tpt-20)°C.

摘要： Nano-composite structures are formed by pre-loading carbon nanotubes (CNTs) into at least one of a plurality of channels running the length of a cartridge, placing the pre-loaded cartridge in a piston chamber of a die-casting machine, creating a vacuum therein, and filing the piston chamber with molten metal to soak the pre-loaded cartridge and fill empty cartridge channels. Pressure is applied via the piston to eject the carbon nanotubes and molten metal from the cartridge channels and inject the nano-composite mixture into a rod-shaped die cavity. The internal diameter of the cavity is equal to or less than the final diameter of the nozzle. The nano-composite mixture is cooled to form a solid nano-composite rod having the first predetermined diameter, wherein the carbon nanotubes are aligned in a non-random manner. Furthermore, drawing down the nano-composite rod to smaller diameter wire further disperses the nanotubes along the length of the wire.
