Units
Condition
- Condition
- EN AW-2618A forged cylindrical blank, initially T61, then overaged 1000 h at 230 degC and air cooled
- Temper
- T61 plus experimental overageing 1000 h at 230 degC
- Heat treatment
- T61: solution anneal 530 degC for 8 h, boiling-water quench, age 195 degC for 28 h, air cool; then overage 230 degC for 1000 h and air cool
- 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 ... 230 degC
- Notes
- Exact EN AW-2618A forging and full T61-plus-overageing schedule. Table 3 values are experimental results reproduced from the authors' CC BY prior study [32]; the current paper states one tensile test per temperature. This severe overaged state is not a registered product temper, EN minimum or design allowable.
