Process for the production of aluminum alloys by spray deposition

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. The object is the production of aluminum alloys having an ultimate stress>/=800 MPa and an elongation>/=5%, as well as the production of alloys which are reinforced by ceramic particles. According to the process, a solid alloy is formed by spray deposition, the alloy is transformed in the hot condition at between 300 DEG and 450 DEG C. and possibly in the cold condition, and the transformed alloy is subjected to solution treatment, quenching and aging.
