TL;DR: In this article, 2195 aluminum alloy was compressed at 300-520°C using a Gleeble 3500-GTC thermo-mechanical testing system and the discontinuous dynamic recrystallization (DDRX) and continuous dynamic re-structure (CDRX), and the results demonstrated that during medium temperatures (300-360°C) deformation the main softening mechanism was DDRX, and at high temperatures (420-520 °C), it was CDRX.

TL;DR: In this paper, an age-hardenable 2219 Al-Cu alloy was severely deformed by multidirectional forging (MDF) at 360-510°C, followed by solution treatment and T8 aging treatment.

TL;DR: In this article, the influence of pre-deformation and subsequent aging on the hardening behavior and microstructure of 2219 aluminum alloy forgings have been analyzed through TEM, Vickers hardness and mechanical property tests.

TL;DR: In this article, isothermal compression tests of the as-homogenized 2219 Al alloy were conducted at temperatures of 260-510°C and strain rates of 0.001-10 s−1 to study the hot deformation characteristics and obtain the optimum processing window for the alloy.

TL;DR: In this paper, an improved ring manufacturing process was proposed for the large 2219 Al alloy rings used to connect propellant tank components of a satellite launch vehicle to each other, and the results showed that the improved process can successfully be applied to manufacture the large 2D alloy rings without formation of macroscopic defects, resulting in a product with fine and uniform grains.
