摘要
研究了不同厚度(0、0.1及0.2 mm)的Ni层在不同的压下条件下对热轧不锈钢复合板结合强度的影响。利用光学显微镜、扫描电镜及EDS能谱仪对热轧不锈钢复合板的组织及界面元素分布等微观特征进行了研究。结果表明,Ni层的加入会明显阻止元素的扩散,并能减少界面氧化物的比例,但在一定程度上会降低界面的结合强度。
The effect of Ni layer thickness( 0,0. 1 and 0. 2 mm) on bonding strength of hot rolled stainless clad steel plate under various rolling conditions was investigated,and the microstructure and interface element diffusion of the hot rolled stainless clad steel plate were studied by means of optical microscope( OM),scanning electron microscopy( SEM) and energy dispersive spectrum( EDS). The results show that elements diffusion through interface is significantly inhibited by Ni layer,and the amount of oxide inclusion also decreases.However,the bonding strength decreases due to the addition of Ni layer between clad and base component material.
