“…Aluminium alloys have a microstructure that can be highly susceptible to intergranular and pitting corrosion, and weathering is recognised as a major cause of structural damage to aircraft structure and coatings (Usmani and Donley, 2002;Russo et al, 2009: Knight et al, 2011, along with long term operations (Ostash et al, 2006), runway deicing chemicals (Huttunen-Saarivirta et al, 2011) and atmospheric pollution and salts (Cole and Paterson, 2009). The degradation of aircraft mechanical components is also connected with mechanical, and corrosion-mechanical (macrocracks) defects, which lead to a decrease in its load-bearing capacity (Ostash et al, 2006). Corrosion has many forms and affects most structural alloys found in airframes: of particular importance is pitting and intergranular corrosion, which can develop into fatigue cracks, stress corrosion cracks or exfoliation (Liao et al, 2008).…”

“…High-strength aluminium alloys are commonly used as the aircraft fuselage materials in the body and wings, while minor amounts of other elements (Cu, Zn, Mg) may be also present in various airframe components (Wei et al, 1998). Aluminium alloys have a microstructure that can be highly susceptible to intergranular and pitting corrosion, and weathering is recognised as a major cause of structural damage to aircraft structure and coatings (Usmani and Donley, 2002;Russo et al, 2009: Knight et al, 2011, along with long term operations (Ostash et al, 2006), runway deicing chemicals (Huttunen-Saarivirta et al, 2011) and atmospheric pollution and salts (Cole and Paterson, 2009).

“…-Alloy D16 .9%; Mg = 1.2-1.8%; Fe and Si ≤ 0.5%; Mn = 0.3-0.9%; Cr ≤ 0.1%; Ti ≤ 0.15%; Zn ≤ 0.25%; admixture ≤ 0.15%), used in the production of plating, framing, stringers, longerons of aircrafts and car bodies (Ostash et al 2006;Lebedev, Chausov 2004); -Alloy 2024-T3 (ASTM B209-14, Cu = 4.35%; Mg = 1.50%; Fe = 0.50%; Si = 0.50%; Zn = 0.25%; Ti = 0.15%; Cr = 0.10%; others ≤ 0.20), which is widely used for the outer covering, in particular, of civil aircraft fuselages (Merati 2005;Smith et al 2000); -Alloy VT22 (GOST 19807-91, Fe = 0.5-1.5%; C = up to 0.1%; Si ≤ 0.15%; Cr = 0.5-1.5%; Mo = 4-5.5%; V = 4-5.5%; N ≤ 0.05%; Ti = 79.4-86.3%; Al = 4.4%; Zr ≤ 0.3%; O ≤ 0.18%; H ≤ 0.015%; others ≤ 0.3%), which is traditionally used for the production of vital components of the airframe and chassis of the passenger and heavy transport aircrafts, in particular, Il-96Т, Il-114 (Shakleina, Zamyatin 2010;Moiseev 2000;Zherebtsov 2012); these alloys ensure reliability of aircrafts, a reduction in their mass, and a long service life of their vital components operated under complex modes of loading (tension, bending, etc. ); -Another test material was steel 04Kh18N10…”

“…An indispensable component of aircraft construction is the performance of endurance field tests and laboratory tests of structural elements and materials (Starke, Staley 1996;Ostash et al 2006). Structural materials used in the production of planting of the aircraft fuselage should be resistant to depletion of plasticity and aging (Merati 2005).…”

“…At the same time, the studies on the condition of structural steels for the critical-purpose objects in long-term service (in particular, power engineering [7][8][9][10][11], aviation [12], chemical [13], gas and oil industries, and transportation systems of marketing hydrocarbons [14][15][16][17][18]) pointed to the significant degradation of metal properties due to the effect of different operating factors. Correspondingly, this problem can also concern the steels of the Shukhov towers.…”
