| Abstract: | Light alloy is the preferred material for modern spaceflight equipment. The functional level and competitiveness of spaceflight equipment are greatly decided by the manufacturing capacity of light alloy components with high performance. To promote the application of advanced light alloy materials and forming techniques in the spaceflight industry, the recent development and research status of light alloy materials, casting, sheet metal forming and additive manufacturing in terms of basic theory, process development, equipment manufacture and engineering application are reviewed. The prospect for advanced light alloy materials and forming techniques is discussed, such as high performance casting magnesium alloy and titanium-aluminum alloy, precision investment casting of magnesium alloy, digital casting, spinning forming, superplastic forming, wire-arc additive manufacturing of titanium and aluminum alloy. |
