间隙元素 [jiàn xì yuán sù]
[化学] interstitial element
- 实验结果表明，随着扩散处理温度的提高和处理时间的延长，未合金化区域中间隙元素的含量降低程度也增大；
Also, the content of the interstitial atoms in the unalloyed zone of iron reduces with increasing diffusion temperature and prolonging holding time. - 研究结果表明，间隙元素C、S、N、O与其它杂质元素对马氏体时效钢的韧性与塑性的影响很大。
The experimental results showed that interstitial elements such as C, S, N, O and other impurity elements have great influences on ductility and toughness of maraging steels. - 碳、氢等间隙元素的扩散分布受到活度和陷阱的强烈影响，碳富集在焊缝熔合区，氢（氚）强烈偏聚在实际熔合线，母材熔合区则同时发生贫碳和贫氢现象。
Carbon accumulates in the fusion zone of the weld metal while hydrogen segregates on the true fusion line. Carbon and hydrogen are simultaneously lacking in the fusion zone of the base metal.
