AA 2099 Heat Treatments
- The as-cast alloy was subjected to two-step homogenization treatment (510°C/12h + 530°C/36h) in the salt bath.
After homogenization treatment, the alloy was annealed at 470°C for 4h in an air furnace, and subsequently extruded at 470°C.
Tensile samples were exposed to six different solution treatment schedules:
STS1 (520°C/1h), STS2 (530°C/1h), STS3 (540°C/1h), STS4 (540°C/4 h), STS5 (550°C/1h) and STS6 (560°C/1h). During solution treatment, samples were directly immersed into a salt bath at these temperatures.
After solution treatment, these samples were rapidly quenched into water, stretched to 2.5% at room temperature, and then subjected to two-step aging treatment (121°C/12h + 152°C/48h).
