| 摘 要： | 通过试验研究，探讨了用于大型船用柴油机气缸套的硼铸铁，Ｂ和Ｐ对硬质相含量及机械性能的影响．指出Ｂ和Ｐ含量与硬质相数量（Ｈｐ）的关系符合下式：Ｈｐ＝１１（１０Ｂ＋Ｐ）－０．３，生产应用表明，用上式计算的硬质相含量与实测值相比，平均误差仅为５．８％

| Abstract: | This paper studied effects of P and B on the hard phase quantity and mechanical properties of boron cast iron used in large marine diesel engine cylinder sleeves The relationship between the P and B contents (wt%) and hard phase quantities (Hp%) has been formularized It is shown in application that the average deviation between the actual value and calculating one is about 5 8% |
