| 英文摘要 | We have studied the effect of isothermal annealing on the evolution of the open-volume defect and the cu precipitate in deformed fe0.15cu, fe0.3cu and fe0.6cu alloys. using the coincidence doppler broadening, positron annihilation lifetime and the s-w couples, the evolution of local electronic circumstance around the annihilation sites, open-volume defects and interaction between open-volume defects and cu precipitates were measured as a function of the isothermal annealing temperatures. cold rolling deformation induced an obvious increment in s parameters due to the formation of open-volume defects. annealing not only resulted in gradual recovery of open-volume defects and cu thermal precipitation, but also promoted the combination and interaction between defects and cu precipitates. the interaction between open-volume defects and cu precipitates was revealed clearly by the view point of s-w relationship. the s-w interaction for the different cumvn complexes was also calculated theoretically by mika-doppler, which supports our experimental observations qualitatively. the results indicate that open-volume defects were formed first after cold rolling, followed by the cu precipitation and recovery of open-volume defects, cu precipitates recovered at the end. it is interesting that the trajectory of (s, w) points with increasing annealing temperature formed a similar closed "parallelogram" shape. it is benefit for revealing the behavior of cu thermal precipitation and their evolution in various cu-bearing steels under thermal treatment. in addition, we also investigated the cu content effect on the cu precipitation in fecu alloys, and the cu precipitate phenomenon was enhanced in higher cu content alloys.
