The specimens were treated by conventional laser peening and a new cyclic laser peening plus thermal microstructure engineering process. The latter treatment supports the benefit of a unique process involving application of layers of laser peening using high energy with large footprint spots combined with interspersed cyclic annealing. Stress measurements by slitting showed the plastic penetration depth of laser peening exceeded shot peening by a factor of 24. 2023-04-19T08:28:11Z 2023-04-19T08:28:11Z 2023 Book https://link.springer.com/article/10.1007/s00170-023-11358-5 https://dlib.phenikaa-uni.edu.vn/handle/PNK/8098 en application/pdf Springer |
