摘　　要：通过研究真空固溶对新型高强铝合金组织和性能的影响,探讨了新型铝合金固溶过程中过烧对其组织及性能影响的机理。结果表明:相同时效机制下,真空560℃高温固溶时,抗拉强度为452 MPa,塑性9.5%;而普通560℃高温固溶时抗拉强度为320 MPa,塑性1.3%。The effects of vacuum solution on the microstrncture and properties of new high-strength aluminum alloy were discussed, and the mechanism of burning affecting its micro-structure and properties during the new type of aluminum solid solution were discussed. The results show that under the same aging mechanism, the vacuum 560℃ high temperature solution, the tensile strength is 452 MPa, plastic is 9.5%. When the general solution temperature is 560℃, the tensile strength is 320 MPa, and plastic is 1.3%.
