Abstract: In this paper, we analyzed the variation rule of precipitates with time in 10Ni3MnCuAl steel during aging at 540 ℃ by three-dimensional atom probe (3DAP) and studied the crystal structure of the NiAl precipitates and their distribution on the martensite by TEM. The results show: the mean volume-equivalent radius of B2-NiAl precipitates increases from 1.13 nm to 2.13 nm, while the number density decreases from 1.70×1022 m-3 at 2 h to 3.40×1021 m-3 at 100 h. The mean volume-equivalent radius of these Cu precipitates increases from 1.04 nm to 2.08 nm, and the number density decreases from 6.04×1021 m-3 at 2 h to 2.00×1021 m-3 at 100 h. As time changes, the shapes of them are changed from sphe-rical to long strips, B2-NiAl precipitates are dispersed on the martensite lath which play a major role in the strengthening of the matrix. There are superlattice in crystal orientation [200] of the matrix.
