It was pointed out that with different chemical composition and different iso - quenching temperature , the structure morphologies of the bainite transition products are different from each other , the ferrite is the indispensable constituent , and whether there is or not carbide existing is not the necessary criterion to discern the bainite 指出不同化学成分和不同等温温度时贝氏体相变产物的组织形态不同,铁素体是贝氏体中不可缺少的组成部分,以及碳化物的存在与否不是判断贝氏体的必要依据。
