Large amounts of aluminum alloys are used in aircraft construction, including Aluminum-Copper coinations and high-strength Aluminum-Zinc materials. Depending on the alloy and the appliion, processes like heat treating and cold working can be used to further strengthen Aluminum alloys.
alloy containing 0.5 percent copper, 2.54 percent magnesium and 5.8 percent zinc was not different than that observed in a ternary aluminum alloy containing 2.47 percent magnesium and 7.4 percent zinc, but that the aging rate decreased, the
Metallurgical silicon metal is a ideal alloying agent for aluminium industry, it will improve the alloy strength. Adding silicon metal to aluminum alloy will make the alloy stronger and lighter, it is more and more widely used in structural engineering, aircraft manufacture and the automotive industry.
Recently, the end-of-service life for aging aircraft and related parts has become a key subject in recycling industries worldwide. Over the next 20 years, approximately 12,000 aircraft currently utilized for different purposes will be at the end of service. Thus, reclaiming
L8 plate contains less magnesium (0.83 wt%) than L2 (1.53 wt%), which shows that L8 is made of A-U4G alloy whereas L2 is made of A-U4G1 alloy. For the series of Breguet 765 Sahara aircrafts, technical clauses and recovered plans indie that A-U4G and
RZ5/ZE41 is used for gearboxes of BR710 engines. Military aircraft use magnesium alloy transmission casings. Elektron WE43 is used in the Pratt & Whtiney F119 gearbox on the F22 aircraft. Magnesium Elektron - Magnesium for Defence Corporate Website
The results showed that the yield strength of magnesium alloy is lower than that of the aluminium alloy with grain size being larger than 2.2 μm. However, the yield strength of magnesium alloy increases steadily upon reducing the grain size to values less than 2.2 μ m, as shown in Figure 7 [ 4 , 34 ].
