Units
Condition
- Condition
- AA7003 high-Si heat, water quenched and artificially aged to study condition T7
- Temper
- T7 as designated by the article
- Heat treatment
- solution heat treatment at 480 degC for 30 min; water quench to room temperature; artificial ageing at 170 degC for 6 h
- Product form
- solid rectangular extruded profile
- Thickness / diameter range
- 20 x 25 mm profile; SSRT geometry in article Figure 2
- Test direction
- SSRT specimen axis relative to extrusion direction is not explicitly stated
- Processing route
- cast and homogenized; preheated to 480 degC; extruded at about 11 mm/s; solution treated, water quenched and artificially aged
- Temperature range
- SSRT and conductivity test temperatures are not stated; air is the retained environment.
- Notes
- Experimental values for one high-Si AA7003 heat and H-WQ-T7 profile condition. The air SSRT strength/ductility values are single-test results; conductivity is a five-measurement mean. The article designates the ageing condition as T7, but these are not EN extrusion minima.
