| 摘要 |
The method involves fabricating a casing (16) comprising a cavity (20) delimited by a boundary which has a reinforcing edge (14), and cutting the casing for removing the reinforcing edge. The casing is fabricated by diffusion bonding fabricated pieces in a preform, and bulging the preform and super plastic forming the casing. The preform is bended and twisted after diffusion bonding operation. |
