| 英文摘要 | The microstructures, irradiation-induced defects and changes of mechanical property of Chinese domestic A508-3 steels after proton irradiation were investigated by TEM, positron lifetime, slow positron beam Doppler broadening spectroscopy and hardness measurements. The defects were induced by 240 keV proton irradiation with fluences of 1.25 x 10(17) ions cm(-2) (0.26 dpa). 2.5 x 10(17) ions cm(-2) (0.5 dpa), and 5.0 X 10(17) ions cm(-2) (1.0 dpa). The TEM observation revealed that the as-received steel had typical bainitic-ferritic microstructures. It was also observed that Doppler broadening S-parameter and average lifetime increased with dose level owing to the formation of defects and voids induced by proton irradiation. The correlation between positron parameters and hardness was found. (c) 2012 Elsevier Ltd. All rights reserved. |
