More Information
Summary:In the present paper, the microstructure and mechanical properties of a precipitation hardening Al–Cu (2219) alloy subjected to cryorolling, low temperature annealing and ageing treatments are reported. Under optimal processing conditions, ultrafine grained microstructure with improved tensile strength (540 MPa) and good ductility (11% tensile elongation) was obtained.
