【摘要】 本文研究了稀土元素镧对含锡和锑的34CrNi3Mo钢的冲击性能的影响;采用SEM及EDS手段研究了镧对含锡、锑的钢断裂方式及在其中形成化合物的情况。结果表明:用稀土金属可以改善低氧、低硫钢中残余元素对钢的冲击性能的危害;镧可以和钢中较低含量的锑作用生成镧锑金属间化合物,并且发现了少量的镧锡金属间化合物。更多还原

【Abstract】 This paper investigates the effect of rare earth element lanthanum on impact property for 34CrNi3Mo containing tin and antimony, the effect of lanthanum on the fracture pattern of the steel with tin and antimony and compound formation condition. The obtained results show that lanthanum can reduce the harmfulness of tin and antimony in the steel with low oxygen and low sulphur contents; lanthanum can react with low content of antimony to form intermetallic compound and a little amount of the compound composed of lanthanum and tin was found.更多还原
