原子探针层析成像表征了BOR60反应堆在376°C和524°C之间的5种温度、14.6 dpa和35.1 dpa剂量下辐照后T91钢的显微组织变化。研究了中子辐照引起的析出和碳化物/基体界面偏析。原子探针层析成像表征表明,在BOR60反应器中辐照的T91钢在376°C至415°C之间形成了富Mn, Ni, Si (MNS-rich)团簇,而在460°C和524°C的高温下没有观察到这种团簇。对富mns簇的数量密度、体积分数和组成进行了表征。在较低温度下辐照后,Ni、Mn、Si和P在碳化物基体界面处偏析,在524℃时只观察到P偏析。
Atom probe tomography has characterised the microstructural changes in T91 steel after BOR60 reactor irradiation at five temperatures between 376  °C and 524  °C to doses between 14.6 dpa and 35.1 dpa. Irradiation-induced precipitation and segregation to carbide/matrix interface induced by neutron irradiation has been characterised. Atom probe tomography characterisation shows that Mn, Ni, Si -rich (MNS-rich) clusters form in T91 steel irradiated in BOR60 reactor at temperatures between 376 °C and 415 °C, which is not observed at higher temperatures 460 °C and 524 °C. The number density, volume fraction and composition of MNS-rich clusters have been characterised. Ni, Mn, Si and P is found to segregate at carbide matrix interface after irradiation at lower temperature and only P segregation is observed at 524 °C.
