Units
Condition
- Condition
- EN AW-2618A forged cylindrical blank in the initial T61 state
- Temper
- T61 (article identifies this as a slightly underaged state)
- Heat treatment
- solution anneal 530 degC for 8 h; quench in boiling water; age 195 degC for 28 h; air cool to ambient
- Product form
- forged cylindrical blank; semi-finished stock for radial compressor wheels
- Thickness / diameter range
- blank dimensions not stated; sampled blocks 16 x 16 x 100 mm from section 3
- Test direction
- axial fatigue sampling region; tensile specimen direction is shown but not textually designated L/LT/ST
- Processing route
- wrought forged cylindrical blank; block extraction and condition-specific heat treatment as stated
- Temperature range
- 20 ... 25 degC
- Notes
- Exact EN AW-2618A forged stock and full T61 schedule. Table 3 tensile values are experimental results reproduced from the authors' CC BY prior study [32]; the 136 HBW value is measured for the current batch. Not an EN minimum or a general forging allowable.
