| 英文摘要 | The effects of different cold rolling reductions (epsilon=7%, 14%, 20%, 27%) prior to aging on the precipitation hardening of the 1460 alloy were studied. The results show that in the sample with epsilon=20%, some dense dislocation walls (DDW) are formed in the Al matrix. The matrix dislocations provide nucleation sites for the T1 phase. Therefore, the precipitation of the T1 is enhanced and its size remains at about 100 nm, and in addition the samples reach the peak strength in a shorter time. The preferable process is 27% cold rolling reduction + 160 degrees C/20 h. The tensile strength and elongation of the samples can be increased to 590 MPa and 8.0%, respectively. |
