| 英文摘要 | The influence of heat treatment on the microstructure and mechanical properties of a 2000 MPa grade Co-free 18Ni maraging steel has been investigated, and the strengthening and toughening mechanisms were discussed. The experimental results show that the hardness of the steel in solution condition is independent of both the solution temperature and the time. A combination of high strength and good toughness can be reached under the peak-aged condition, where the ultimate strength is over 2100 MPa, and the elongation and K-Ic are 9% and 70 MPa(.)m(1/2), respectively. The TEM observation revealed that a great deal of nanometer size precipitates, such as Ni-3(Mo, Ti), is distributed in a high density dislocation matrix of the steel treated with peak-aged condition, which realizes a better match of strength and toughness. The precipitation strengthening in the present steel obeys the modified Orowan mechanism. |
