| 摘 要： | 文章就美国标准ASTMA-247与GB7216-1987对铸铁的石墨形态分级作了详细介绍。美国材料与实验学会ASTMA-247中将铸铁中可能出现的石墨形态分成7类，其中对灰铸铁的石墨形状分为5种，从A型到E型，而GB7216—1987把灰铸铁的石墨形状分为6种，即A型到F型。同时将石墨片长又分成8级。

| Abstract: | This paper introduced the graphite form classification of gray cast iron in ASTMA-247 and GB7216-1987. In The various forms in which graphite occurs in cast irons have been classified into seven types. In ASTMA-247, the graphite form in cast iron has been classified into seven types, five types in gray cast iron, that is from A type to E type. In GB7216-1987, the graphite form in gray cast iron has been classified into six types, that is from A type to F type, and the graphite flake length has been classified into eight types. |
