Abstract The machining allowance of the wall thickness of the formed blank hemisphere is decorated reasonably, and the dimensions of the superplastic forming mold surface is calculated. Through the analysis of material deformation mechanism in the process hemisphere superplastic-forming, the reverse direction preforming mold type surface is designed to achieve the purpose of uniform blank wall thickness and to make it satisfy the requirements of subsequent processing size.
