| 1 | Effect of aging treatment on irradiation-induced segregation of high Mn-Cr steel显示文摘To investigate the effect of aging treatment on irradiation-induced segregation of high Mn-Cr steel, specimens for electron-beam irradiation were prepared from the high Mn-Cr austenitic steel which was solution treated at 1 373 K for 1 h and aging treated at 573 K for 1 000 h, respectively. The electron-beam irradiation was performed at 573 K up to doses of 5.4 dpa in a 1 250 kV HVEM and irradiation-induced segregation analyses were carried out by an EDX in a 200 kV FE-TEM. The results show that void formation is not observed in both solution treated and aging treated ones. The amount of Cr segregation at the grain boundary decreases in the aged one; however, that of Mn is not changed in solution treated one. | D.S.BAE S.P.LEE Y.R.CHO H.TAKAHASHI | 2011 | Transactions of Nonferrous Metals Society of China2011，21，A01： | 1 |
