摘　　要：研究了原始基体组织分别为铁素体和珠光体的球铁等淬后显微组织与性能的差别，结果表明：原始组织为珠光体基体的球铁，等淬后其显微组织中的白亮区较多，硬度值较高，而冲击韧度略低。In this paper, the difference of the microstructure and mechanical properties of ADI between ferritic and pearlitic prematrix structure was studied. It is shown that with a pearlitic prenatrix Structure, there are more untransformes austenite areas after austemper,which lead to a little higher hardness and lower impact toughness.
