Abstract: |
The process and control method of SPF/DB were studied on the base of the regional enhanced TA15 titanium alloy four-sheet structure. Preforming and forming experiment of the regional enhanced TA15 titanium alloy four-sheet structure were carried on. A regional enhanced TA15 titanium alloy four-sheet structure was got. The microstructure changes of sheet and solid frame were analyzed before and after the forming by OM. Diffusion bonding surfaces were observed among panel, core and solid frame by SEM. |
