氢在硅系铸铁中的分布

Distribution of Hydrogen in Silicon Series Cast Iron

研究了不同含硅量的硅系铸铁中氢的分布后得出：无论是化学成分分析，还是微区成分分析，随铸铁中含硅量的变化，氢的含量也发生相应的变化．这就是硅系铸铁在自然状态下，其含氢量的分布特点．文中对此做了初步的理论分析．

A conclusion has been drawn throughthe investigation of the distribution of hydrogen in silicon series cast iron: Both chemical composition analysis and micro-analysis with the variation of silicon content the content of hydrogen changes correspondingly and this is the characteristic of hydrogen of distribution in natural state in as-cast state) in silicon series cast iron. This paper has also give an initial theory analysis which is of significance to imvestigate imto the machanism op silicon brittleness of silicon cast iron.
