    Abstract: The invention involves a system and method, and multi-layer pad, for processing an alloy ingot or other alloy workpiece to reduce thermal cracking and reduce friction between the workpiece and the forging die. The present invention includes the use of a multi-layer pad when forging a workpiece, which can be positioned between the workpiece and the forging die. The multi-layer pad comprises two layers secured together to form a sleeve, and another layer positioned within the sleeve. The present disclosure is also directed to alloy workpieces processed according to the methods described herein, and to articles of manufacture made from these alloy workpieces.

    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: A method of processing a non-magnetic alloy workpiece comprises heating the workpiece to a warm working temperature, open die press forging the workpiece to impart a desired strain in a central region of the workpiece, and radial forging the workpiece to impart a desired strain in a surface region of the workpiece. In a non-limiting embodiment, after the steps of open die press forging and radial forging, the strain imparted in the surface region is substantially equivalent to the strain imparted in the central region. In another non-limiting embodiment, the strain imparted in the central and surface regions are in a range from 0.3 inch/inch to 1 inch/inch, and there exists no more than a 0.5 inch/inch difference in strain of the central region compared with the strain of the surface region of the workpiece. An alloy forging processed according to methods described herein also is disclosed.

    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.
