研究了He、H和Si三重离子同时辐照对两种SiC/SiC复合材料（HNS复合材料（使用Hi-Nicalon型S SiC纤维）和TSA复合材料（使用Tyranno SA SiC纤维））在1000 °C下组织演变的影响。用透射电镜观察了10 dpa辐照后SiC/SiC复合材料的微观结构。TSA复合材料基体中几乎没有氦泡形成，但HNS复合材料基体的晶界处观察到许多氦泡和一些裂纹。另一方面，在HNS和TSA复合材料的纤维织物中没有观察到气泡和裂纹。在两种复合材料中均未观察到纤维与碳层在辐照区域后的脱粘现象。在此辐照条件下，TSA复合材料的微观结构稳定性优于HNS复合材料。
The effect of simultaneous triple ion irradiation of He, H and Si on microstructural evolution of two kinds of SiC/SiC composites (HNS composite (using Hi-Nicalon type S SiC fiber) and TSA composite (using Tyranno SA SiC fiber)) at 1000 °C has been investigated. The microstructure observations of SiC/SiC composites irradiated to 10 dpa were examined by transmission electron microscopy. He bubbles were hardly formed in matrix of TSA composite, but many helium bubbles and some cracks were observed at grain boundaries of matrix of HNS composite. He bubbles and cracks were not, on the other hand, observed in the both fiber fabrics of HNS and TSA composites. Debonding between fiber and carbon layer following irradiation region was not observed in the both composites. Under these irradiation conditions, TSA composite showed the better microstructural stability against ion beams irradiation than one of HNS composite.
