fatigue crack growth rate, the evolution of the surface temperature was also monitored. The collected data were used for further investigation on entropy generation. All the data needed to be validated before proceeding with the development of MLR. The approach applied in this study begins by determining the fatigue crack development and the evolution of temperature. The study made use of the commercial AZ31B magnesium alloy. AZ31B is a wrought magnesium alloy with both notable room-temperature ductility and strength.
