6061-T6 aluminium standard heat treating process. T6 temper 6061 has been treated to provide the maximum precipitation hardening (and therefore maximum yield strength) for a 6061 aluminium alloy. It has an ultimate tensile strength of at least 290 MPa (42 ksi) and yield strength of at least 240 MPa (35 ksi).
Aluminium–scandium alloys (AlSc) are aluminum alloys that consist largely of aluminium (Al) and traces of scandium (Sc) as the main alloying elements.In principle, aluminium alloys strengthened with additions of scandium are very similar to traditional nickel-base superalloys in that both are strengthened by coherent, coarsening resistant precipitates with an ordered L1 2 structure.
Note that the term aircraft aluminium or aerospace aluminium usually refers to 7075. [65] [66] 4047 aluminium is a unique alloy used in both the aerospace and automotive applications as a cladding alloy or filler material. As filler, aluminium alloy 4047 strips can be combined to intricate applications to bond two metals. [67]
The addition of ceramic particles in general increases the strength of the material while having a tradeoff on material ductility. For example, a Al-Al 2 O 3 composite can increase the yield strength of cast Al 6061 alloys from 105 to 120 MPa and increase the young’s modulus from 70 to 95 GPa. [9]
T5 temper 6063 has an ultimate tensile strength of at least 140 MPa (20,000 psi) in thicknesses up to 13 millimetres (0.5 in), and 130 MPa (19,000 psi) from 13 mm (0.5 in) thick, and yield strength of at least 97 MPa (14,000 psi) up to 13 millimetres (0.5 in) and 90 MPa (13,000 psi) from13 to 25 mm (0.5 to 1 in).
By comparison, annealed type 316 stainless steel has a density of 8000 kg/m 3, modulus of 193 GPa, and tensile strength of 570 MPa. [23] Tempered 6061 aluminium alloy has a density of 2700 kg/m 3, modulus of 69 GPa, and tensile strength of 310 MPa, respectively. [24] Ti-6Al-4V standard specifications include: [25] [26]
6082 aluminium alloy is an alloy in the wrought aluminium-magnesium-silicon family (6000 or 6xxx series). It is one of the more popular alloys in its series (alongside alloys 6005 , 6061 , and 6063 ), although it is not strongly featured in ASTM (North American) standards.
In one study, strain hardening exponent values extracted from tensile data from 58 steel pipes from natural gas pipelines were found to range from 0.08 to 0.25, [1] with the lower end of the range dominated by high-strength low alloy steels and the upper end of the range mostly normalized steels.
