The Alumniurn-Copper-Lithi arn (Al-C u-Li) alloy s are used as aero space materi als du e to thei r low den sity , hig h modulus of elasticity, good resistance to fatigue crack propagation , and excelle nt cryogenic properties. In the current experime nt, Al-Cu-L i (2 195) allo y is se lected to study the effect of the ag ing process on mechanical propertie s. The 2 195 all oy in sheet form is supplied by Lockheed-Marti n, New Orleans. The as-received 2 195 alloy sheet is solution-treated at 5 10 ° C for one hour followed by …
