Units
Condition
- Condition
- EN AW-8011A industrial cold-rolled foil process chain, Technology A, from RFS through FBA/FCA
- Temper
- process states RFS, 1C, IA, 2C, FBA and FCA; no registered temper assigned
- Heat treatment
- intermediate anneal 400 +/- 10 degC for 4 h; final batch or continuous anneal within the source's 270-320 +/- 5 degC process window
- Product form
- industrially hot-rolled sheet followed by cold-rolled 0.09 mm foil
- Thickness / diameter range
- 6.00 +/- 0.05 mm hot-rolled re-roll foil stock; 1.50 +/- 0.05 mm after 75 percent reduction; 0.09 +/- 0.05 mm after 95 percent reduction from the intermediate-annealed state
- Test direction
- composition not directional; tensile method was RD; cup-ear angles are relative to rolling direction
- Processing route
- Technology A: hot-rolled RFS; first cold roll; 400 +/- 10 degC/4 h intermediate anneal; second cold roll to 0.09 mm; final batch or continuous anneal
- Temperature range
- Annealing temperatures are process parameters, not a service-temperature validity range.
- Notes
- Exact EN AW-8011A industrial research material following the article's Technology A cold-rolling chain. Table 1 measured composition and Table 4 measured cup-ear/calculated texture anisotropy are transcribed directly. The article's Figure 5 strength and elongation curves are not digitized, and the reproduced STANDARD EN AW-8011A composition row is not imported. No registered temper, density, elastic constants, bulk hardness, product-standard minimum or design allowable is claimed.
