Units
Condition
- Condition
- AA6261 source-labeled present alloy and remelted/stir-cast unreinforced base control
- Temper
- not stated
- Heat treatment
- not stated; the paper does not identify a registered temper
- Product form
- laboratory remelted/stir-cast base-control tensile and hardness specimens
- Thickness / diameter range
- cast stock approximately 55 mm diameter x 150 mm long; tensile specimen nominal 6.00 mm diameter with 30.0 mm gauge length
- Test direction
- not stated
- Processing route
- starting AA6261 was shredded and melted; unreinforced 500 g control was stir cast at 1123 K; tensile specimens were CNC-machined from cast stock
- Temperature range
- Tensile testing is reported at 28 degC. The hardness temperature text is malformed, so no hardness-test temperature is assigned and no temperature extrapolation is allowed.
- Notes
- Exact-grade research-instance data, not current EN product-standard minima or wrought-product allowables. The article contains identity and method inconsistencies: it prints EN AW-626 instead of EN AW-6261, elsewhere prints 6066/Al6066, gives yield strength as 98 MPa in Table 2 but 151 MPa for the experimental base-control tensile row in Table 6, labels the tensile conditions ASTM E10/18 although specimen preparation cites ASTM E8/E8M-09, and prints a malformed hardness-test temperature range. PropLib retains both yield observations with their table-specific scope, does not assign a test temperature, and excludes every nano-reinforced composite value.
