7075 aluminium alloy (AA7075) is an aluminium alloy with zinc as the primary alloying element. It has excellent mechanical properties and exhibits good ductility ...
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.
That must have been a mistake. The linked article Extra super duralumin and successive aluminium alloys for aircraft states that in 1935 the 7075 was developed. - 1935-Nen (Shōwa 10-nen) tōji sudeni chō jurarumiso (Super Duralumin) gōkin wa kaihatsu sa rete itaga Wildkatzen 09:22, 23 May 2019 (UTC)
7075 may refer to: 7075 Sadovnichij, a main-belt asteroid discovered in 1979; 7075 aluminium alloy This page was last edited on 3 September 2020, at 19:09 (UTC) ...
Can be formed similar to 7075; Annealing provides superior formability and noticeable decline in workability following solution heat treatment; Form in “as-quenched” -W temper condition for best results [3]
The combination of high strength and fracture toughness properties and corrosion resistance makes 7065 suitable as a replacement for 7010, 7050, 7075, 7475 and other alloys for critical intermediate thickness applications. [3] Spar, rib, and integrally machined structural parts for new, derivative, or retrofit aircraft. [3]
7068 alloy is a 7000 series aluminium-zinc alloy registered with the US Aluminium Association and produced to AMS 4331 (chemical composition and mechanical properties) and AMS 2772 (heat treatment). 7068 alloy ‘A’ and ‘B’ tensile data and fatigue properties have been ratified for inclusion in MIL Handbook 5 / MMPDS.
Like most other highly alloyed alloys, 7022 is a high strength alloy, with yield strength of 370 MPa. Designed to be resistant to stress corrosion cracking, it has decent corrosion and oxidation resistance comparable to 7075 aluminium alloy [1] but worse than 7039 aluminium alloy. Good machinability, thermal conductivity and dimensional ...
