Abstract
Aluminium-lithium alloys have received considerable attention from the aircraft industry because of their light weight, high strength to weight ratio and stiffness. The Lital A sheets are supplied in the cold rolled condition . This operation introduces residual stresses . In this report the residual stress distribution across the thickness of an asreceived Lital A sheet of thickness 7 .S9 mm is reported . The stress measurements were done by XRD technique and the layer removal by electropolishing . The residual stresses at the surface, both in the rolling and perpendicular directions, were compressive. The magnitude of stress in the rolling direction was about 1 .75 times that in the perpendicular direction . The compressive stresses decreased steeply with depth and became tensile stress of low magnitude after certain depth.
