Femtosecond laser shock peening of ultra-thin-walled Ti-6Al-4V: study on surface integrity and high cycle fatigue mechanism

Journal of Materials Research and Technology
Ultra-thin-walled structural components are widely used in aeroengines, but they are prone to high-cycle fatigue (HCF) failure due to cyclic alternating stresses during operation.
