Abstract: Split pass forging a workpiece to initiate microstructure refinement 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: 596427 A forging die heating apparatus and method is disclosed. The apparatus comprises a burner head (420) comprising a plurality of flame ports (426) configured to impinge flames (429) onto one or more forging surface regions of at least one forging surface of a forging die (410). The burner head (420) is configured to receive and combust fuel and an oxidizing gas. The burner head (420) comprises a first portion (432, 432') with one or more first flame ports (429) and a second portion (434, 434') comprising one or more second flame ports (429'). The first portion is movable relative to the second portion to conform an orientation of at least one first flame port (29) to an orientation of a first forging surface (442) region of the forging die (410').

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 an alloy ingot or other alloy workpiece to reduce thermal cracking may generally comprise depositing a glass material onto at least a portion of a surface of a workpiece, and heating the glass material to form a surface coating on the workpiece that reduces heat loss from the workpiece. The present disclosure also is directed to an alloy workpieces processed according to methods described herein, and to articles of manufacture including or made from alloy workpieces made according to the methods.

Abstract: A forging die (412', 414' ) heating or preheating apparatus (420) comprises a burner head (422) comprising a plurality of flame ports (426). The burner head (422) is oriented to compliment an orientation of at least a region of a forging surface of a forging die and is configured to receive and combust a supply of an oxidizing gas and a supply of a fuel and produce flames at the flame ports. The burner portion (432) can be movable with respect to the burner portion (432') to conform at least a portion of the burner head (422) to an orientation of the forging surface (416') of the forging die (410'). The plurality of flame ports (426) are thus configured to impinge the flames onto the forging surface (416', 418') of the forging die to substantially uniformly heat at least the region of the forging surface of the forging die.

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.
