摘要
概要介绍可锻铸铁的新的韧断特性参数—V_(GC)宏观形式与细观形式参数间的关系,并作了宏观V_(GC)的测试.初步得到了可锻铸铁临界空穴扩张比的数据,并作了一些分析。
This paper primarily introduces a now ductil fracture feature parameter of malleable iron-a relationship between V_(GC) parameters of macroscopic form and microscopic form, and make some tests of the macroscopic V_(GC).The data of the critical void growth natio of malleable iron are obtained in their initial forms and some further analyses on these data are made.
