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: 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 has a plurality of ports burning a mixture of fuel and an oxidising gas substantially comprising oxygen. In further embodiments the burner head (420) comprises a first portion (432) with one or more first flame ports (426) and a second portion (429) comprising one or more second flame ports (426’). The first portion is movable relative to the second portion to conform an orientation of at least one first flame port (429) to an orientation of a first forging surface region (442) of the forging die (410’). The disclosed apparatus allows a forging die to be pre heated faster than conventional preheating techniques which use a single torch.

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: Se describe un aparato calentador o pre-calentador (420) de troquel de forjar (412´, 414´) que consiste en un cuerpo del quemador (422) que tiene una pluralidad de puertos de llamas (426). El cuerpo del quemador (422) está orientado para cumplir con una orientación de al menos una región de la superficie de forjado de un troquel de forjar y está configurado para recibir y quemar un suministro de un gas oxidante y un suministro de un combustible y producir llamas en los puertos de llamas. La parte quemador (432) se puede mover con respecto a la parte quemador (432´) para conformar al menos una parte del cuerpo del quemador (422) a una orientación de la superficie de forjado (416´) del troquel de forjar (410´). La pluralidad de puertos de llamas (426) están configurados de manera que incidan con las llamas en la superficie de forjado (416´, 418´) del troquel de forjar para calentar de manera prácticamente uniforme al menos la región de la superficie de forjado del troquel de forjar.

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.
