| 英文摘要 | Fe-cu systems, model alloys of nuclear reactor pressure vessel (rpv) steels, heat treatments by annealing and quenching, are studied by the positron annihilation technique and high-resolution sem. the different effect of annealing and quenching on the formation of cu precipitates was discussed. the ultrafine cu precipitates, which are formed in fe-x wt.% cu (x = 1.0 and 1.5) alloys after thermal annealing, are observed clearly and no obvious cu precipitates were found in the quenched alloys. the annealing temperature has an effect on the concentration of cu precipitates, which leads to a change of the proportion of positron annihilation in the cu precipitates, and this can be reflected by the change of the w parameters. positron annihilation doppler broadening spectroscopy results show that cu precipitates formed during annealing at 1173 k still exist when the annealing temperature is higher than 1453 k. sem measurements were used to observe the size and the distribution of cu precipitates in the samples, after using different annealing temperature.
