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: The present disclosure relates to developing a method of working that provides sufficient strain to a metallic material to initiate microstructure refinement mechanisms efficiently through forging, while limiting ductility issues. In this regard, the invention provides split pass forging a workpiece to initiate microstructure refinement that 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: Un método para procesar una pieza de trabajo de aleación no magnética comprende calentar la pieza de trabajo a una temperatura de trabajo en caliente, tratar por forjado libre a presión la pieza de trabajo para impartir una tensión deseada en una región central de la pieza de trabajo, y tratar por forjado radial la pieza de trabajo para impartir una tensión deseada en una región superficial de la pieza de trabajo. En una modalidad no taxativa, después de las etapas de forjado libre a presión y forjado radial, la tensión impartida en la región superficial es sustancialmente equivalente a la tensión impartida en la región central. En otra modalidad no taxativa, la tensión impartida en la región central y en la región superficial se encuentra en un intervalo de entre 0,3 pulg./pulg. y 1 pulg./pulg., y existe una diferencia de no más de 0,5 pulg./pulg. en la tensión de la región central en comparación con la tensión de la región superficial de la pieza de trabajo. También se describe un forjado de aleación procesado de acuerdo con los métodos descritos en el presente.
