铍元素具有良好的性能，是模拟堆中子倍增器的候选材料之一，在600-800℃下需要有良好的性能。因此，铍类化合物有望与结构材料具有良好的相容性。在本研究中，首先进行了Be12Ti与SS316LN的相容性试验，以评估铍与结构材料的相容性。在800℃时，Be12Ti与SS316LN之间的反应层厚度在1000℃后约为30 pm，而金属铍的反应层厚度为300 pm在600℃下反应1000h后，Be12Ti和Be的反应层厚度分别小于10um和100um。对Be12Ti与SS316LN的相容性进行了评价，结果表明，在600-800℃高温下，Be12Ti的相容性好于金属铍与SS316LN的相容性。证明了铍在演示堆中作为中子倍增器的优势。(C)2002 Elsevier Science B.V.保留所有权利。
Beryllides have good properties and are one of the candidate materials for the neutron multiplier of the DEMO reactor in which good performance is required at 600-800 degreesC. Therefore, a good compatibility with structural materials is expected for the beryllides. In this study, a compatibility test between Be12Ti and SS316LN was carried out as first Step to evaluate the compatibility between beryllides and structural materials. The thickness of the reaction layer between Be12Ti and SS316LN at 800 degreesC after 1000 It was approximately 30 pm, whereas that of beryllium metal was 300 pm. At 600 degreesC after 1000 h, the thickness of the reaction layers as to Be12Ti and Be was less than 10 and 100 mum, respectively. The compatibility between Be12Ti and SS316LN was evaluated and Be12Ti was perfectly better than that between beryllium metal and SS316LN at high temperature (600-800 degreesC). The advantage of beryllides as a neutron multiplier in the Demo reactor was proved. (C) 2002 Elsevier Science B.V. All rights reserved.
