Condition
- Condition
- EN AW-2030 square bar after the article's controlled annealing cycle
- Temper
- article-described annealed condition; no registered O temper claimed
- Heat treatment
- heat from room temperature to 420 degC over 1 h; hold 420 degC for 1 h; cool to 250 degC over 1 h; hold 250 degC for 1 h; stop oven and cool to room temperature
- Product form
- square-section wrought bar
- Thickness / diameter range
- 50 x 50 mm source-bar section; tensile geometry per article Table 1
- Test direction
- tensile direction relative to bar processing direction not stated
- Processing route
- commercial wrought bar, machined tensile specimens, controlled annealing
- Temperature range
- The tensile-test temperature used to identify the hardening constants is not stated.
- Notes
- The exact alloy, bar section, annealing cycle and fitted Hollomon parameter semantics are retained. The article does not state the initial temper, tensile direction, test temperature, replicate count, fit interval or fit uncertainty. No tensile/yield strength, elongation, standard minimum or design allowable is inferred from the plotted curve.
