摘要:Large-scale explosive welded composite plates are important materials for nuclear fusion reactor vessels, and have high requirements for mechanical properties and crack detection tests. In order to meet the requirements, titanium/steel explosive welded composite plates were manufactured under different gas media, and the effect of gaseous media on the interfacial microstructure and mechanical properties of the composite plates was evaluated. The results show that there are significant differences in the interface morphology and mechanical properties of the explosive welded composites under different gaseous media. Unlike traditional explosive welding under air, a low density helium medium smooths the welding process and creates a more stable periodic wave at the interface. In addition, helium gas as an inert gas effectively inhibits the formation of oxides at the interface and improves the mechanical properties and welding quality.
