Embodiment Construction
[0027] Implementation examples such as Figure 1-7 As shown, for the superplastic forming / diffusion connection of a four-layer thin-walled mesh part with a solid structure made of TA15 titanium alloy, the specific steps are as follows:
[0028] (1) Preparation of raw materials and forming female mold: such as figure 1 As shown, the raw materials include an upper panel and a lower panel with a thickness of 1 mm, an upper core plate and a lower core plate with a thickness of 1 mm, and a solid structural part a and a solid structural part b. The cavity of the forming female mold is the grid part to be formed Shape; raw material is TA15 titanium alloy;
[0029] (2) Forming of two-layer panels: such as figure 2 As shown, the two-layer panels are placed in the forming female mold, and the two-layer panels are placed up and down; then the two-layer panels and the forming female mold are heated to the superplastic forming temperature (about 900°C) of the raw material TA15 titanium ...
