In this paper The hardness of grey iron is related to the amount and fineness of pearlite in the matrix, and is effected to a great extent by the amount of primary austenite and its eutectoid structure. 结果表明,灰铸铁的硬度不仅与基体中珠光体的含量和细化程度有关,而且在很大程度上还取决于铸铁结晶过程中初生奥氏体量及其共析转变的结果。
The pre eutectoid ferrite transformation initiated at the original austenite grain boundaries and formed a net structure. 先共析铁素体沿原始奥氏体晶粒边界生长,形成网状结构。
