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: Una modalidad de un método de refinación del tamaño de grano de fase alfa en una aleación de titanio alfa y beta comprende trabajar una aleación de titanio alfa y beta a una primera temperatura de trabajo dentro de un intervalo de primera temperatura en el campo de la fase alfa y beta de la aleación de titanio alfa y beta. La aleación se enfría lentamente desde la temperatura de trabajo. Tras completar el trabajo y enfriar lentamente desde la primera temperatura de trabajo, la aleación comprende una microestructura primaria de partículas de fase alfa globularizada. La aleación se trabaja a una segunda temperatura de trabajo dentro de un intervalo de segunda temperatura en el campo de la fase alfa y beta. La segunda temperatura de trabajo es menor que la primera temperatura de trabajo. Se trabaja a la tercera temperatura de trabajo en un intervalo de tercera temperatura en el campo de la fase alfa y beta. La tercera temperatura de trabajo es menor que la segunda temperatura de trabajo. Luego de trabajar a una tercera temperatura de trabajo, la aleación de titanio comprende un tamaño de grano deseado de fase alfa refinado.

Abstract: A casting system and method. The casting system can include an energy source and a hearth, which can have a tapered cavity. The tapered cavity can have a first end portion and a second end portion, and the tapered cavity can narrow between the first and second end portions. Further, the tapered cavity can have an inlet at the first end portion that defines an inlet capacity, and one or more outlets at the second end portion that define an outlet capacity. Where the cavity has a single outlet, the outlet capacity can be less than the inlet capacity. Where the cavity has multiple outlets, the combined outlet capacity can match the inlet capacity. Further, the cross-sectional area of the tapered cavity near the inlet can be similar to the cross-sectional area of the inlet.

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 forging die (412', 414' ) heating or pre-heating 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.
