Mechanism of Precipitate Microstructure Affecting Fatigue Behavior of 7020 Aluminum Alloy
The effect of different precipitate microstructures obtained by different heat treatments on fatigue behavior of 7020 aluminum alloy was investigated. The fine Guinier Preston I (GPI) zones in the under-aged alloy can be repeatedly sheared by dislocations produced in cyclic loading, making the fatig...
