Improvement of Fatigue Characteristics of Friction Stir Welded A6061-T6 Applying Shot Peening

Article Preview

Abstract:

Recently, researchers have developed the method as a harmless the crack by the surface modification. For the purpose of contributing to reliability improvement of the A6061-T6 structure by harmless method, the following research was carried out: The tensile residual stress of friction stir welding was added by shot peening, resulting in a more significant compressive residual stress than that of the base metal. The effect of the surface crack aspect ratio on the maximum harmless crack depth (a_hml) of A6061-T6 was evaluated for residual stress distribution. The detectable depth was evaluated in the relationship between a_hml and the maximum detectable crack depth (a_NDI) by non-destructive inspection (NDI).
