论文摘要
在这项研究中，通过在室温（RT）上以不同的氦辐射剂量为5E15、1E16、5E16和1E17CM-2，在室温（RT）上以不同的氦照射剂量诱导的TI3SIC2 MAX相材料的微观结构变化，通过X-Ray Intraction Intraction（Gixrd）和Raman Spartra进行了表征。 TI3SIC2的辐照损伤过程可以根据氦照射剂量的水平将三个阶段大致分为三个阶段：（1）对于低损伤剂量，仅晶体和受损的Ti3SIC2出口； （2）在较高的照射剂量下，还有一些损坏的TIC相； （3）具有更高辐照剂量的剂量，在样品内也可以发现晶体相位。此外，TI3SIC2上的450C 5E16CM-2氦辐射已证实，Ti3SIC2在较高温度下具有更高的辐射耐受性，这意味着TI3SIC2可能是在高温环境下起作用的未来结构性和燃料涂料的潜在结构和燃料涂料。
In this study, the microstructure changes of Ti3SiC2 MAX phase material induced by helium irradiation and evolution with a sequence of different helium irradiation doses of 5E15, 1E16, 5E16 and 1E17cm-2 at room temperature (RT) were characterized with grazing incidence X-ray diffraction (GIXRD) and Raman spectra analysis. The irradiation damage process of Ti3SiC2 can be roughly divided into three stages according to the level of helium irradiation dose: (1) for a low damage dose, only crystal and damaged Ti3SiC2 exit; (2) at a higher irradiation dose, there is some damaged TiC phase additionally; (3) with a much higher irradiation dose, crystal TiC phase could be found inside the samples as well. Moreover, the 450C 5E16cm-2 helium irradiation on Ti3SiC2 has confirmed that Ti3SiC2 has much higher irradiation tolerance at higher temperature, which implies that Ti3SiC2 could be a potential future structural and fuel coating material working at high temperature environments.
