Characterisation of Residual Stress due to Fillet Rolling on Bolts Made of a Nickel Base Superalloy Conference Paper uri icon


  • This paper investigates residual stress due to fillet rolling on bolts made of ATI 718Plus┬« superalloy. Incremental hole drilling, neutron diffraction and neutron transmission have been used to assess residual stress near the bolt head fillet. A compressive residual stress field was identified in the first 0.5 mm from the surface. Post fillet rolling solution anneal can relieve the residual stress at the fillet.
