    Abstract: The present disclosure relates to developing a method of working that provides sufficient strain to a metallic material to initiate microstructure refinement mechanisms efficiently through forging, while limiting ductility issues. In this regard, the invention provides split pass forging a workpiece to initiate microstructure refinement that comprises press forging a metallic material workpiece in a first forging direction one or more times up to a reduction ductility limit of the metallic material to impart a total strain in the first forging direction sufficient to initiate microstructure refinement; rotating the workpiece; open die press forging the workpiece in a second forging direction one or more times up to the reduction ductility limit to impart a total strain in the second forging direction to initiate microstructure refinement; and repeating rotating and open die press forging in a third and, optionally, one or more additional directions until a total amount of strain to initiate microstructure refinement is imparted in an entire volume of the workpiece.

    Abstract: A rnethod f refining grain size in a workpiece conrising a metallic material selected from titanium and a titanium alloy, the method comprising: heating the workpiece to a workpiece forging temperature range within an alpha+beta phase field of the metallic material, wherein the workpiece comprises a cylindrical-like shape and a starting cross sectional dimension; upset forging the workpiece within the workpiece forging temperature range; and multiple pass draw forging the workpiece within the workpiece forging temperature range; wherein multiple pass draw forging comprises incrementally rotating the workpiece in a rotational direction followed by draw forging the workpiece; and wherein incrementally rotating and draw forging is repeated until the workpiece comprises the starting cross-sectional dimension. 25840394v ~~~~ RAW K\N~NtV~S d NN .\ t 4 t so W '> W \WKNT& Is>2

    Abstract: 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.

    Abstract: Methods of refining the grain size of titanium and titanium alloys include thermally managed high strain rate multi-axis forging. A high strain rate adiabatically heats an internal region of the workpiece during forging, and a thermal management system is used to heat an external surface region to the workpiece forging temperature, while the internal region is allowed to cool to the workpiece forging temperature. A further method includes multiple upset and draw forging titanium or a titanium alloy using a strain rate less than is used in conventional open die forging of titanium and titanium alloys. Incremental workpiece rotation and draw forging causes severe plastic deformation and grain refinement in the titanium or titanium alloy forging.

    Abstract: rotas de processamento para titânio e ligas de titânio. métodoks de refinar o tamanho de grão de titânio e ligas de titânio incluem forjadura de múltiplos eixos de taxa deformação elevada controlada termicamente. uma taxa de deformação elevada aquece adiabaticamente uma região interna da peça de trabalho durante forjadura e um sistema de controle térmico é utilizado para aquecer uma região de susperfície externa até a temperatura de forjadura de peça de trabalho, enquanto a região interna é deixada resfriar até a temperatura de forjadura de peça de trabalho. um método adicional inclui forjadura por estiramento e por pressão múltipla de titânio ou uma liga de titânio utilizando uma taxa de deformação menor do que é utilizada em forjadura de matriz aberta convencional de titânio e ligas de titânio. a rotação incremental de peça de trabalho e forjadura por estiramento causa deformação plástica severa e resfriamento de grão na forjadura de titânio ou liga de titânio.
