根据夹杂物的形态和分布,标准图谱分为A、B、C、D和DS五大类。这五大类夹杂物代表最常观察到夹杂物的类型和形态:(1)A类(硫化物):具有高的延展性,有较宽范围形态比的单个灰色夹杂物,一般端部呈圆角。最早C.E.Sims将硫化物(FeS)分成三类:Ⅰ为球状硫化物;Ⅱ为片状或棒状硫化物;Ⅲ为尖角状硫化物。,Ⅰ类和Ⅱ类硫化物产生于协同共晶,Ⅲ类硫化物产生于离异共晶,如CaS、FeS、MnS、MnS-FeS等。在
According to the shape and distribution of inclusions, the standard map is divided into A, B, C, D and DS five categories. These five categories of inclusions represent the most commonly observed types and forms of inclusions: (1) Category A (sulfides): single gray inclusions with high ductility and a wide range of aspect ratios, with generally rounded ends angle. The earliest C.E.Sims sulfide (FeS) will be divided into three categories: Ⅰ for the spherical sulfide; Ⅱ for the sheet or bar sulfide; Ⅲ for the sharp-shaped sulfide. The sulfides of type I and type II are produced in synergistic eutectic. The type III sulfides are derived from divorced eutectic, such as CaS, FeS, MnS and MnS-FeS. in
