摘要
In the retrogression process as the first step of RRA heat treatment applied to AA7075-T651 alloy, it was kept at 200 °C for 10 minutes and was shock cooled by predeforming the same by 5-10% at this temperature and reaging process was applied at 120 °C for 24 hours in the Argon protected heat treatment furnace. It was indicated that elongation % of the samples is increased after the thermo-mechanical process applied during RRA process.
