| Methods of refining the grain size of a titanium alloy workpiece include beta annealing the workpiece, cooling the beta annealed workpiece to a temperature below the beta transus temperature of the titanium alloy, and high strain rate multi-axis forging the workpiece. High strain rate multi-axis forging is employed until a total strain of at least 1 is achieved in the titanium alloy workpiece, or until a total strain of at least 1 and up to 3.5 is achieved in the titanium alloy workpiece. The titanium alloy of the workpiece may comprise at least one of grain pinning alloying additions and beta stabilizing content effective to decrease alpha phase precipitation and growth kinetics. | ||||||

| 169 | Radially convergent hot forging apparatus and method | US414003 | 1989-09-28 | US4996863A | 1991-03-05 | Philip S. Keeler |
| Disclosed is a method and apparatus for hot forging an elongated cylindrical hot billet formed of lightweight metal alloy or metal matrix composite material into an integral high strength structural member having at least two extensive walls projecting outwardly in different directions from the billet axis, with principal metal grain structure running approximately parallel to the outward extent of the walls. The hot forging is accomplished by bringing a plurality of radially convergent hot die segments from a full open release position to an intermediate position where they first convergently engage the hot billet, and gradually further converging the die segments to a closed position to forge the billet by engaging them with a pyramidal or conical frustum cavity formed in a press member, which cavity conforms to the external configuration of the die segments in the closed position. | ||||||

| 173 | Cross transport press | US120232 | 1980-02-11 | US4333329A | 1982-06-08 | Hans Richner |
| Apparatus for periodically sensing and cooling the end face of one or more rams of an automatic cross transport press. In a cross transport press, on the press frame (1) there is mounted a sensing rocker (9) which executes a periodical rocking movement about a horizontal axis (A) in the work rhythm of a carriage (2) provided with rams (5). The movement of the sensing rocker (9) is transmitted from the carriage (2) through a connecting rod (20), a transmission lever (17) and the two rocker arms (8) to sensing elements (27) equipped with cooling sprinklers. The slightly angled transmission lever (17) rests upon a stop (15) and is retained upon the stop (15) by a spring (25). If a sensing element (27) encounters an obstacle, then the press is stopped; simultaneously the transmission lever (17) lifts from the stop counter to the return force of the spring (25), whereby any damage is prevented. The sensing rocker can be pivoted upwards into a rest position if a pneumatically loaded piston is used instead of the spring (25). | ||||||

| A worn titanium blade for a gas turbine engine has metal displaced at its aerofoil tip, so that the aerofoil can be dressed to restore it to length. The titanium is not amenable to cold forging, or to being entirely heated, a forge is therefore provided which has dies which contact only the immediate area containing the metal to be displaced. The dies are heatable so as to heat the said area by conduction and powered so as to apply suitable pressure in a way which brings about isothermal displacement of the titanium. | ||||||
