Characterization of Fatigue and Crack Growth on AZ31B Magnesium Alloy
This research studied the characteristics of fatigue and Crack Growth (CG) behaviour of AZ31B magnesium alloy at room temperature when the material was used for designing. The experiments were carried out using a fatigue machine, which involved the experimental testing of stress–strain material and fatigue and CG tests. The fatigue test was conducted using a standard ASTM E8 and dog bone samples at 90, 80, 70, 60 and 50% of applied yield stress. Meanwhile, a CG test was done using ASTM E647 standard Compact Tension (CT) and specimen at 90% of yield stress. Both tests were conducted under a sinusoidal cycle by applying the Constant Amplitude Loading (CAL) at a frequency of 10 Hz. The fatigue endurance showed that at 1 × 106, the stress was 48 Mpa using the Basquin equation prediction. The predicted lives were in good agreement with an R2 of 0.91. The CG behaviour of the specimen, indicating a fatigue CG (a-N) with failure of the structure, and the Paris Law constants were determined.
