| Large, non-unitarily forged shaft workpieces such as a crankshaft have successive shaft features inductively heated and forged without cool down between each sectional forging process. The temperature profile along the axial length of the next section of the shaft workpiece to be inductively heated and forged is measured prior to heating, and the induced heat energy along the axial length of the next section is dynamically adjusted responsive to the measured temperature profile to achieve a required pre-forge temperature distribution along the axial length of the next section prior to forging. | ||||||

| A forging tool for precision forging of components of intermetallic or high-temperature stable phases with high yield stresses and shapeable at temperatures up to 1400° C. is made of graphite with a low-melting metal or a low-melting metal alloy infiltrated into its open-pored cavities, where metal carbides are created by heat treatment and form with the graphite a two-phase material hardened by subsequent quenching. The tool features high strength thanks to the yield stress increasing as the temperature increases at forging temperatures up to 1400° C., and is oxidation-resistant. It is electrically conductive, and has a low heat capacity, so that rapid inductive heating of the tool involving only low energy expenditure, short forging cycles and an inexpensive isothermic shaping process are possible. It has good lubrication properties, low wear and low manufacturing costs. | ||||||

| The present invention provides methods and apparatus improving the dimensional accuracy of forged components. Uniformity of like component details is sought and a specific object is to provide a die package for forming closely toleranced appendages integrally with a central disk structure from which the appendages extend. In one effective embodiment incorporating concepts of the present invention, the forging dies include a stationary die and a movable die comprising at least two separately movable elements which are mounted on a common axis with the stationary die. A plurality of arcuate die segments are adjacently placed in cylindrical array about the stationary and movable dies. The arcuate die segments form cavities of the inverse geometry of the appendages to be formed and in at least one embodiment are interlocked to prevent tilting of the segments in the die package. The movable die elements are sequenceable to form a billet of material into a workpiece having an intermediate configuration, and subsequently into a workpiece of final configuration. In at least one embodiment, pressure pads are disposed against one of the movable dies to prevent displacement of that die by the billet material as the intermediate configuration is formed. | ||||||
