硫化物是钢中普遍存在的夹杂物.随着冶炼工艺以及钢中某些合金元素含量的不同,将生成不同类型的硫化物.钢中硫化物通常主要以MnS、FeS、(Mn,Fe)S以及其他硫的复合夹杂物存在;当加入钛和稀土等合金后,则主要形成Ti_4C_2S_2、RExSy和RE_2O_2S等类复杂硫化物.硫化物夹杂的数量、组成、形状、粒度以及在钢中的分布,将对钢的性能产生不同程度的影响,因此,国内外广泛采用了金相、化
Sulfides are ubiquitous inclusions in steel.With the smelting process and the content of some alloying elements in steel, different types of sulfides will be formed.The sulfides in steel usually mainly consist of MnS, FeS, (Mn, Fe) S and other sulfur inclusions.When titanium and rare earth alloys were added, mainly complex sulfides such as Ti_4C_2S_2, RExSy and RE_2O_2S were formed.The number, composition, shape, grain size and distribution of sulfide inclusions in the steel , Will have different degrees of impact on the performance of steel, therefore, widely used at home and abroad metallographic, chemical
