摘要
本文对大断面球铁断口进行了宏观分类,讨论了断口宏观、微观形貌与组织及力学性能之间的关系;研究了灰斑和黑斑断口产生的机制。
The macro-fracture features of heavy section ductile iron were classified. The relation between fracture morphology,matrix composition and mechanical properties of heavy section ductile iron was discussed. The formation mechanism of grey and black spots has been studied.
