摘要
利用光学显微镜、扫描电镜、能谱等手段,研究了悬浮铸造FeB-Q235复合材料的界面反应及元素的扩散、偏聚。研究发现,悬浮铸造的复合材料界面反应元素迁移距离短,生成的高硼相和夹杂物在界面上集中分布;正火处理能够减少界面上的高硼相,但是对夹杂物的形态和分布没有影响,正火处理后界面上的晶粒细化程度高于基体。
The element diffusing and segregation in the interface of FeB-Q235 composite prepared by suspension casting was studied by optical microscope, SEM and EDS. The experiment results show that, the element moving distance is short, the producted high-boron phase and impurity distributes in the interface of FeB-Q235 composite. The high-boron phase in the interfacial of FeB-Q235 composite can be reduced by normalizing. But normalizing doesn＇t change the shape and distribution of impurity. After normalizing, the size of crystal near the interfacial of FeB-Q235 composite is smaller than that of the matrix.
