| Abstract | The evolution of microstructures and properties of aged 2A97 alloy at 165 degrees C after quenching, and at 135 degrees C after quenching and 4% plastic deformation for various times were investigated. The results show that theta ''/theta' and delta' phases are the main strengthening phases of aged alloy at 165 degrees C for 18 h after quenching, which shows high tensile strength and ductility resulting from increasing amount of T(1) phase distributed heterogeneously in matrix. With increasing aging time at 165 degrees C, the number density of theta ''/theta', T(1), and delta' increase, and the length of T(1) decreases, while the length of theta ''/theta' increases. Stretch before aging fines the size of theta ''/theta' and T(1), and stimulates the precipitation and uniform distribution of them, so it yields higher strength for the alloy aged at 135 degrees C for 36 h after quenching and stretch, which is 441 MPa, 519 MPa, and 7.4% for sigma(0.2), sigma(b), and sigma(5), respectively, than the alloy aged at 165 degrees C after quenching. |
