设计并试验了一种由二氧化硅、氧化铝和氧化钇组成的低活性微晶玻璃，作为二维熔合级碳化硅/碳化硅的连接材料。用欧洲活化系统Easy-2007程序包模拟了玻璃中元素的中子诱发放射性。对三种不同类型的接头试件进行了四点弯曲试验，测试了接头的机械强度。在室温下测得的弯曲强度大于120 MPa，大多数情况下复合材料都是破坏的。(C)2008爱思唯尔B.V.保留所有权利。
A low-activation glass-ceramic based on silica, alumina and yttria has been designed and tested as joining material for 2D fusion grade SiC/SiC. Neutron-induced radioactivity of elements present in the glass has been simulated by European Activation System EASY-2007 code package. The mechanical strength of the joined SiC/SiC has been tested by 4-point bending on three different kinds of joined samples. Bending strength higher than 120 MPa has been measured at room temperature, with composite failure in most cases. (c) 2008 Elsevier B.V. All rights reserved.
