Abstract
The present invention provides a method of forming a component () from an alloy sheet of material () having at least a Solvus temperature and a Solidus temperature of a precipitation hardening phase, the method comprising the steps of: heating the sheet () to above its Solvus temperature; initiating forming the heated sheet () between matched tools () of a die press and forming by means of plastic deformation towards a final shape whilst allowing the average temperature of the sheet () to reduce at a first predetermined rate A; interrupting the forming of the sheet for a predetermined first interruption period P1 prior to achieving said final shape; and, during the interrupt holding the sheet of material with reduced or no deformation and allowing the average temperature of the sheet to reduce at a second predetermined rate B lower than or equal to the first predetermined rate in order to allow for a reduction in dislocations and completing the forming of the heated sheet into the final shape whilst allowing the sheet to cool at a third rate C greater than said second rate B.
