摘要：Study of crack growth and its propagation under fatigue load is important as the crack growth can end up inpremature failure of components. Such failures have to be avoided especially in power plants and aerospace applicationssince the components in these applications are subjected to extreme temperatures. In the present work, studies have beencarried on the fatigue crack growth of aluminium 2024 alloy. The test specimens were annealed and cryotreated andsubjected to fatigue crack growth (FCG) tests as per ASTM E-647 standards. The fatigue crack growth behaviour has beenanalysed and explained based on the microstructure. The FCG test results of the heat treated and untreated specimens clearlyindicate significant improvement of the fatigue life and fracture toughness of cryotreated specimens.
