A method of drawing a material into sheet form includes forming a preform comprising at least one material as a large aspect ratio block wherein a first transverse dimension of the preform is much greater than a second transverse dimension substantially perpendicular to the first transverse dimension. A furnace having substantially linearly opposed heating elements one spaced from the other is provided and the heating elements are energized to apply heat to the preform to create a negative thermal gradient from an exterior surface along the first transverse dimension of the preform inward toward a central plane of the preform. The preform is drawn in such a manner that the material substantially maintains its first transverse dimension and deforms across its second transverse dimension.

The invention relates to metallurgy, and more particularly to producing titanium alloy-based materials with specific mechanical properties for the manufacture of fasteners for use in various fields of industry and preferably in the aerospace industry. The claimed material for the manufacture of high-strength fasteners is made from a titanium alloy containing alloying elements in the form of ?-stabilizers, #-stabilizers and neutral strengthening elements, the rest being titanium and unavoidable impurities. The size of a beta-subgrain in the structure of the material, which is subjected to solution annealing and aging, does not exceed 15 ?m. The material for the manufacture of high-strength fasteners is produced in the form of round bar with a diameter of up to 40 mm or round wire with a diameter of up to 18 mm, which are subjected to solution annealing and aging After solution annealing and aging, the material has an ultimate tensile strength of greater than 1400 MPa, an elongation of greater than 11%, a reduction in area of greater than 35% and a double shear strength of greater than 750 MPa. An intermediate blank for drawing is obtained by melting an ingot of titanium alloy, thermomechanically processing the ingot to obtain a forged billet and then rolling same. An intermediate blank for drawing is also obtainable using a powder metallurgy method.

The present invention relates to a method for forming a hollow 26 of a ferritic FeCrAI alloy into a tube 2. While tubes made of powder metallurgical, dispersion hardened, ferritic FeCrAI alloys are commercially available, hollows made of FeCrAI alloys so far can hardly be formed into tubes of small dimensions. The major reason for the problems in forming hollows of a ferritic FeCrAI alloy into a finished product is that FeCrAI alloys are brittle. It is therefore an aspect of the present invention to provide a tube 2 made of a ferritic FeCrAI alloy having arbitrary small dimensions. Furthermore, it is an aspect of the present invention to provide a machine 1 and a method for forming a tubular hollow 26 into a finished tube 2 of a ferritic FeCrAI alloy. At least one of the above aspects is addressed by a method for forming a hollow into a tube 2 comprising the steps providing the hollow 26 of a ferritic FeCrAI alloy, heating the hollow 26 to a temperature in a range from 90 C. to 150 C., and forming the heated hollow 26 by pilger milling or drawing into the tube.
