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: 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: Forge lubrication processes are disclosed. A solid lubricant (38) sheet is placed between a workpiece (30) and a die (34; 36) in a forging apparatus. Force is applied to the workpiece (30) with the die (34; 36) to plastically deform the workpiece. The solid lubricant sheet (38) decreases the shear factor for the forging system and reduces the incidence of die-locking.

Abstract: A thermo-mechanical treatment process is disclosed. A nickel-base alloy workpiece is heated in a first heating step to a temperature greater than the M23C6 carbide solvus temperature of the nickel-base alloy. The nickel-base alloy workpiece is worked in a first working step to a reduction in area of 20% to 70%. The nickel-base alloy workpiece is at a temperature greater than the M23C6 carbide solvus temperature when the first working step begins. The nickel-base alloy workpiece is heated in a second working step to a temperature greater than 1700 F (926 C) and less than the M23C6 carbide solvus temperature of the nickel-base alloy. The nickel-base alloy workpiece is not permitted to cool to ambient temperature between completion of the first working step and the beginning of the second heating step. The nickel-base alloy workpiece is worked to a second reduction in area of 20% to 70%. The nickel-base alloy workpiece is at a temperature greater than 1700 F (926 C) and less than the M23C6 carbide solvus temperature of the nickel-base alloy when the second working step begins.

Abstract: One embodiment of a method of refining alpha-phase grain size in an alpha-beta titanium alloy comprises working an alpha-beta titanium alloy at a first working temperature within a first temperature range in the alpha-beta phase field of the alpha-beta titanium alloy. The alloy is slow cooled from the first working temperature. On completion of working at and slow cooling from the first working temperature, the alloy comprises a primary globularized alpha-phase particle microstructure. The alloy is worked at a second working temperature within a second temperature range in the alpha-beta phase field. The second working temperature is lower than the first working temperature. The is worked at a third working temperature in a third temperature range in the alpha-beta phase field. The third working temperature is lower than the second working temperature. After working at the third working temperature, the titanium alloy comprises a desired refined alpha-phase grain size.

Abstract: A method of processing an alloy workpiece to reduce thermal cracking may comprise spraying a metallic coating material onto at least a portion of a surface of the alloy workpiece to form a surface coating metallurgically bonded to the alloy workpiece. The surface coating may be more ductile than the alloy workpiece and reduces heat loss from the alloy workpiece.

Abstract: Processes and methods related to processing and hot working alloy ingots are disclosed. A metallic material layer is deposited onto at least a region of a surface of an alloy ingot before hot working the alloy ingot. The processes and methods are characterized by a reduction in the incidence of surface cracking of the alloy ingot during hot working.
