ABSTRACT Numerous pressure process parameters were used to cavitation strengthen Aluminum lithium alloy (8090Al-Li). We used cavitation water jet peening to extend the fatigue life N/cycle of an 8090 lithium aluminium alloy (8090Al-li) over an unpeened sample. Surface morphology, compressive residual stress (CRS), and microhardness increase to 4,699μm, -147MPa, and 173HV with a 30 MPa peened area CWJP pressure increment. This is demonstrated by the data. The CWJP induces CRS in the 8090Al-li, which increases its resistance to fatigue crack growth (FCG), fatigue crack initiation (FCI), and fatigue striation, while also decreasing the dimple size. When the strain was influenced, the fatigue life of 8090al-li was increased by 61.9965 %, 91.89 %, and 111.74 %, respectively. The study details the fatigue N/cycle of 8090Al-Li using CWJP. |
