AI Technical Summary
Existing technologies make it difficult to manufacture Al0.3CoCrFeNi/304L composite materials that possess both high strength, toughness, and excellent high-temperature mechanical properties, and there are interference and boundary effect problems during the explosive composite process.
By designing high-entropy alloy components, calculating explosion parameters, and performing explosive composite processing, combined with molecular dynamics simulation and VST formula to optimize collision velocity, and using an auxiliary detonation plate to mitigate boundary effects, a high-quality composite of Al0.3CoCrFeNi and 304L was achieved.
High-strength and tough composite plates with yield strength of 592-606 MPa, tensile strength of 653-702 MPa, elongation after fracture of 38-49%, shear strength of 270-290 MPa, and flexural strength of 840-900 MPa were prepared, meeting the requirements for protective armor, with a bonding quality of more than 95%.
