Fine-grained 7075-0 sheets for aircraft taper-rolled stringers have been developed. The new material exhibits fine grain size (40 microns) and no grain growth after slight cold-reduction followed by solution treatment. Because of the fine grain size, the new material exhibits excellent properties compared with coarse-grained material (200 microns) fabricated by conventional process. The new material is now massproduced and applied to taper-rolled stringers for the latest civil transports.
