Abstract
A part is manufactured from a composite material containing an aluminum alloy as a metal matrix. Blanks are prepared from a billet of the composite material, and worked on in a press, while they are held at a temperature ranging from the solidus temperature, Ta, of the aluminum alloy minus 50 (Ta−50) deg. C. to Ta deg. C. At a temperature below (Ta−50), the blanks have too high a resistance to plastic deformation to be easily worked on. At a temperature over Ta, a liquid phase is produced and makes the blanks likely to crack easily during plastic deformation.
