Si、Mn对厚断面铸态铁素体球铁组织与机械性能的影响

The Effects of Si and Mn onthestructures and Mechanical ProPertles of As-cast Heavy Section Ferritic Ductile Iron

在实验室条件下，研究了Ｓｉ、Ｍｎ对厚断面铸态铁大体球铁基体组织及机械性能的影响；确定了铸态高韧性厚断面铁素体球铁与之相适应的Ｓｉ、Ｍｎ含量。

The effects of Si and Mn on the matrix structures and mechanical proporties of as-cast heavy sectionductile iron were studied,the suitable contents of Si and Mn for high toughness heavy section as-cast ferritic ductileirOn were deterInined under the laboratory conditions.
