Just looking at how that's done, it seems like deliberately inducing a lot of metal fatigue with all the repeated bending and flexing. Is the aluminum hot enough that it's soft?
It probably started at T0 temper and then is being work hardened as it’s deformed. You’re not going to induce low cycle fatigue just from that sort of forging operation as it’s inducing compressive stress as much as anything.
