摘要： Producing a Ni superalloy component in which the superalloy has a γ phase matrix containing intermetallic γ′ precipitates. Providing a Ni superalloy casting of the component; solutioning the component by heat treating the casting under vacuum and/or in an inert atmosphere at a temperature above the γ′ solvus to homogenise the γ phase; quenching and ageing the solutioned component to grow intermetallic γ′ precipitates in the homogenised γ phase. Before the solutioning step: heat treating the casting to produce a thermally grown oxide on the surface, oxide adherent to supress volatilisation of Ni from the surface of the casting during the solutioning heat treatment. Performing the solutioning step under a Ni vapour pressure which is sufficient to supress volatilisation of Ni from the surface of the casting during the solutioning heat treatment. During the solutioning heat treatment the component is encapsulated in a container protecting the casting from Si-doped contaminants.

摘要： A mould for casting a component in a directional solidification casting process having a preferred direction of grain growth (non-axial ) comprises a shell defining a cavity for receiving molten material. The cavity defines a three dimensional shape made up of a finished component geometry portion (42, 43, 44) and a sacrificial geometry portion (45) wherein the sacrificial geometry portion (45) includes a notch (48) which is shaped and positioned so as to, in use, contain high angle grain boundaries between dendritic growth in the preferred direction (non-axial ) and dendritic growth in a competing direction to the preferred direction (axial ) within the sacrificial geometry portion of a casting solidifying in the mould.

摘要： An apparatus for the simultaneous casting of multiple components using a directional solidification process includes; a pouring cup arranged on a centreline, an array of moulds encircling the pouring cup and centre line, an array of feed channels extending from the pouring cup to a top end of each mould, and a heat deflector. The heat deflector comprises a wall arranged between the array of moulds and the centreline extending along the length of the moulds and in thermal contact with the moulds.
