Abstract
Tests of specimem of Al-Cu-Li alloys have shown that fatigue cracks in these materials sometimes grow in directions different from the appli ed load. This article examines the effect of different stages of aging on the rate of fatigue-crack growth (FCGR) and direction of crack pro pagation in tests conducted on extrusions of alloy 1450 to determine f racture toughness (K-Ic) and resistance to fatigue.
