“…The fatigue fracture surfaces of Al-Cu-Li alloy under different pre-rolled conditions in the final fracture region are presented in Figure 4. These fractographs exhibit the typical characteristics of ductile fracture, which include clearly visible dimples [11,25]. Furthermore, the surfaces show an array of dimples and voids of various sizes, along with broken coarse second-phase particles and some noticeable tear ridges.…”

“…As noted by Zhao [24], rolling an alloy plate can yield a structure similar to the "hard surface and tenacious core" generated by shot peening. Chen et al [25] studied the impact of pre-rolling on the FCG rate of 2195 Al-Li alloy. Their findings revealed that as the pre-rolling reduction increased, so did the density of the T 1 phase and the yield strength of the alloy, ultimately leading to an increase in the FCG rate and a consequent reduction in fatigue life.…”
