针对目前关于磷对石墨化影响问题尚无一致意见,作者较详细地研究了磷对Fe46%C合金组织和结构的影响。结果表明,随着磷含量的提高,石墨的尺寸增大,共晶团尺寸缩小。并从热力学角度分析了磷含量和温度对碳的活性影响。针对目前关于磷对石墨化影响问题尚无一致意见,作者较详细地研究了磷对Fe46%C合金组织和结构的影响。结果表明,随着磷含量的提高,石墨的尺寸增大,共晶团尺寸缩小。并从热力学角度分析了磷含量和温度对碳的活性影响。 相似文献

At present, in cast iron fine melting, lowering phosphorus concentration with no loss ofother favorable elements at the same timeseems to be a problem, which still has notbeen solved thoroughly. Therefore, looking foran appropriate nodulizer to modify the morphology of phosphide eutectic, especially inhigh strength cast iron, is necessary. On theother hand, phosphorous can also exhibit itsfaVorable effect on mechanical properties aswell as processing behaviors. For instance,gray cast iron cont… 相似文献
