Effect of Different Rolling Techniques on Fatigue Crack Propagation in 5052 Al Alloy

In the present study, the fatigue crack propagation in 5052 Al alloy processed through different cryogenic rolling methods has been investigated in detail. The solution-treated 5052 Al alloy was subjected to different cryogenic rolling methods such as cryorolling (CR), cryo groove rolling (CGR) and...

Description
Summary:In the present study, the fatigue crack propagation in 5052 Al alloy processed through different cryogenic rolling methods has been investigated in detail. The solution-treated 5052 Al alloy was subjected to different cryogenic rolling methods such as cryorolling (CR), cryo groove rolling (CGR) and cryo groove rolling followed by warm rolling (CGW). The CR, CGR and CGW processed samples exhibit threshold stress intensity value (Δ K th ) of 4.88, 6.5 and 5.5 MPa m 1/2 , whereas ST sample possesses Δ K th of 3.75 MPa m 1/2 . The formation of UFG grains of size 125–200 nm as observed through the TEM images along with improved elastic strength of the cryo deformed samples are responsible for the improvement of Δ K th .
