Units
Condition
- Condition
- laboratory continuous-cast non-Cu AA7021 in the article's peak-aged condition
- Temper
- study-designated T6 peak ageing; not a product-standard certification
- Heat treatment
- solution treatment at 470 degC for 4 h; ageing at 124 degC for 32 h
- Product form
- continuous-cast billet; machined hardness and ASTM E8 tensile specimens
- Thickness / diameter range
- billet dimensions not stated; hardness specimen 10 x 10 x 10 mm; tensile geometry per article Figure 1
