摘要
通过对不同含 Si 量、P 量的铸态球铁及铁素体球铁在不同温度下的冲击试验,作者详细考察了 Si 量、P 量对冲击韧性与脆性转变温度的影响。结果表明(?)和 P 量增加,球铁易脆性破坏、脆性转变温度明显升高。
In this paper,the influence of the Si content and P content in nodular cast iron and nodular ferrite cast iron their impact toughness and britle transformation tempera- tare are investigated in detail based on the impact tests under different temperaturres with the specimen containing different Si content and P content.Results show that brit- tleness cracks and its brittle temperature greatly increases if Si and P are added.
