ductile 托福GREGMAT

For ductile, what is the nodularization method?  In-mold?  Sandwich?  Tundish?  Fischer Converter?  Cored wire?  Other?

对于球,球化方式是什么？

The mixed nodulizer can be applied for the key middle and small section casts of ductile iron.

可以在质量要求高的中小截面重要球铸件上应用。

The RE(Y)-Mg-Si-Fe nodularizer had been used to cast heavy sectioned high ductile nodular iron cooling wall castings.

应用钇基重稀土镁复合球化剂，铸造厚大断面高球冷却壁，成功地获得了铸件中心部位铸态高能。

Cataclastic texture which came from brittle deformation made the jadeite quality bed, but the mylonitic texture which resulted from ductile deformation made the jadeite quality good.

在强大剪切应力和钠质流体的共同作用下，铬矿的淡化作用是形成绿色的主要原因。

In the ductile shear belt,the alteration and zonation of tectonite and wall rock are obviously,and miliolite belt,quartz,iron pyrite,ankerite alteration belt and gold mineralization belt are trinity.

剪切带内构造岩、围岩蚀变分带明显,并具有典型的“(超)糜棱岩—石英、黄矿、白云石化—金矿化”等“三位一体”成矿特征。
