摘要

This study pioneers the integrated fabrication of magnesium corrugated-core sandwich structures using wire-arc directed energy deposition (WA-DED). Two sandwich structures—V-type and X-type—were designed with optimized deposition paths to achieve comparable grain morphology while enhancing strength. The compression properties and failure modes of the two corrugated-core sandwich structures were examined through quasi-static compression tests. Results showed that the V-type structure exhibited a higher specific compressive strength (93 MPa∙cm³/g) than the X-type structure (72 MPa∙cm³/g). Both finite element analysis and experimental compression tests indicated that failure occurred at the midsection of the corrugated core. This work offers valuable insights for the efficient fabrication of high-strength corrugated-core sandwich structures.
