摘要： 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.

摘要： Forge lubrication processes are disclosed. A solid lubricant sheet is placed between a workpiece and a die in a forging apparatus. Force is applied to the workpiece with the die to plastically deform the workpiece. The solid lubricant sheet decreases the shear friction factor for the forging system and reduces the incidence of die-locking.
