“…The higher the rotational speed, the higher the deformation rate, and the more obvious the crushing effect. Therefore, compared to the high deformation temperature, the high strain rate in RZ has a greater influence on dynamic recrystallization [ 30 ]. The higher the rotational speed, the greater the crushing effect and the more unfavorable for the nucleation of new grains [ 31 ].…”

Experiments of friction plug weld AA6082-T6 aluminum alloy hole defects were carried out by using the method of friction auxiliary heating between the shaft shoulder and base metal. The grain refinement of the joint’s re-crystallized zone was significant, and there was obvious preferred orientation. Under the condition of other constant parameters, the rotational speed of the plug increases as the grain size of RZ increases and the component of High Angle Grain Boundaries decreases. The effect of a high deformation rate on dynamic re-crystallization is greater than that of high deformation temperature. The deformation texture component increased from 1600 r/min to 2000 r/min, while the re-crystallization texture component increased first and then decreased.
