摘要	The precipitating behavior of Cu-riched particles during isothermally aging and its effect on hardness and damping capacity of Fe-16Cr-2.5Mo-1.0Cu damping alloy have been investigated by atom probe tomography (APT) and scanning transmission electron microscopy (STEM). The results show that aging at temperature range from 400 degrees C to 700 degrees C has minor influence on grain size. During aging at temperature below 400 degrees C, the supersaturated Cu dose not precipitate out. While aging temperature is 450 degrees C, a relatively small number of Cu-riched particles can be observed and the particle radius is small (1.5 +/- 0.56 nm). With a further increasing aging temperature, the Cu-riched particles increase to 3.21 +/- 0.52 nm at 550 degrees C and further grow to 12.88 +/- 2.02 nm at 700 degrees C. As compared with 450 degrees C, the particle number increases significantly at 550 degrees C, and then decreases at 700 degrees C. Due to the stable grain size and no precipitate, the hardness keeps constant below 400 degrees C. With a further increasing aging temperature, the hardness increases gradually and reaches peak value aging at 600 degrees C due to the increase of Cu-riched particle number. The damping capacity significantly depends on particle. Once there appear Cu-riched particles, the damping capacity decreases obviously. During aging, both hardness and damping capacity of the alloy can keep stable when temperature is below 400 degrees C.
