    Abstract: . An apparatus that controls the flow of a stream of metal, such as produced from the bottom of a hearth, includes a cylindrical metallic nozzle body (28) having a hollow wall which includes a slit extending substantially parallel to the axis of the cylinder so that there is no electrical continuity around the nozzle wall across the slit. The walls of the cylinder are preferably formed of hollow tubes through which cooling water is passed. A sensor senses a performance characteristic of the apparatus, such as the temperature of the nozzle body. An induction heating coil (46) surrounds the nozzle body, and a controllable induction heating power supply (48) is connected to the induction heating coil to provide power. A controller (64) controls the power provided to the induction heating coil by the induction heating power supply responsive to an output signal of the sensor (56), so that a selected performance characteristic of the apparatus may be maintained.

    Abstract: Processes for fabricating components (10) to have two or more regions (12,14) with different grain structures, and components (10) produced by such processes. First and second preforms (22,24;42,44) are fabricated to comprise interface surfaces (28,48) at which the preforms (22,24;42,44) can be joined together. The first and second preforms (22,24;42,44) are formed of first and second precipitation-strengthened alloys, respectively, and the first alloy differs from the second alloy by having a higher solvus temperature or a higher grain refiner content. The preforms (22,24;42,44) are joined together to form an article (30,50) comprising first and second portions (32,34;52,54) formed by the first and second preforms (22,24;42,44), respectively, and corresponding to first and second regions (12,14) of the component (10), respectively, and the interface surfaces (28,48) of the preforms (22,24;42,44) form a joint (38,58) between the first and second portions (32,34;52,54) of the article (30,50). A supersolvus heat treatment is performed on the article (30,50) so that greater grain growth occurs in the second portion (34,54) than in the first portion (32,52).
