摘要：A process for the production of a series 7000 aluminum alloy (Al-Zn-Cu- Mg)with a high level of mechanical strength and good ductility, by spray deposition. Theobject is the production of aluminum alloys having an ultimate stress≧800 MPa and anelongation≧5%, as well as the production of alloys which are reinforced by ceramicparticles. According to the process, a solid alloy is formed by spray deposition, the alloyis transformed in the hot condition at between 300° and 450° C. and possibly in the coldcondition, and the transformed alloy is subjected to solution treatment, quenching andaging.
