Effect of low temperature on fatigue and crack propagation behavior of aeronautic aluminium alloy
Fatigue and crack growth tests were performed on two categories of the common aeronautic aluminum- alloys 2524-T3 and 7050-T7451 at ambient temperature of 25 ℃ and cryogenic temperature of –70 ℃, in order to investigate the fatigue and crack propagation properties and micro mechanism. The test resul...
