【摘要】 本文研究了镧稀土合金制取铸铁时,镧稀土合金加入量,孕育处理、铈稀土合金与镧稀土合金之比和硫量对铸铁组织的影响。结果表明,镧稀土合金可做为高强度灰铸铁和蠕墨铸铁的一种新型变质剂。更多还原

【Abstract】 This Paper deals with the influence of the Lanthanum rare earth alloy added in different arnount, inoculation, the ratio of Cerium rare earth alloy to Lanthanum rare earth alloy and sulfur contents on the structure of Cast Iron when the Cast iron is prcduced with Lanthanum rare earth alloy. The results show that the Lanthanum rare earth alloy Can be used as a new type of modifying agents of the high strength grey cast iron and compacted graphite Cast iron.更多还原
