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。
Through the impact tests on ductile iron and ferritic ductile iron with different contents of Si and P, the effects of Si and P contents on impact toughness and brittle transition temperature were investigated in detail. The results showed that the amount of (?) And P increased, the brittleness of the ductile iron decreased and the brittle transition temperature increased obviously.
