摘要： Methods of refining the grain size of titanium and titanium alloys include multiple upset and draw forging. Titanium and titanium alloy workpieces are heated to a workpiece forging temperature within a workpiece forging temperature range in the alpha+beta phase field. The workpiece may comprise a starting cross-sectional dimension. The workpiece is upset forged in the workpiece forging temperature range. After upsetting, the workpiece is multiple pass draw forged in the workpiece forging temperature range. Multiple pass draw forging may comprise incrementally rotating the workpiece in a rotational direction followed by draw forging the workpiece after each incremental rotation. Incrementally rotating and draw forging the workpiece is repeated until the workpiece comprises substantially the same starting cross-sectional dimension.

摘要： A constructing-and-forging method for preparing homogenized forged pieces comprises: preparing preformed billets: cutting off a plurality of continuous casting billets, milling and smoothing surfaces of the billets to be welded, performing vacuum plasma cleaning operation to the surfaces to be welded, stacking the plurality of billets and sealing around the surfaces in a vacuum chamber by electron beam welding; forge-welding and homogenizing the preformed billets: heating the preformed billets to a certain temperature in a heating furnace and taking the heated preformed billets out of the heating furnace, forging the preformed billets by a hydraulic press, then using three-dimensional forging to disperse the welded surfaces such that composition, structure and inclusion of the interface areas are at the same level as those of the bodies of the billets. Cheap continuous casting billets are stacked and forge welded.

摘要： 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.
