用热轧穿孔的方法获得10MnVNb/12Cr双金属复合钢管,通过金相显微镜、环境扫描电镜(ESEM)、能谱仪(EDS)观察界面附近微观组织及元素在界面的分布情况,采用X射线衍射仪和显微硬度计分析界面附近物相及物相变化带来的界面两侧金属硬度起伏,研究不同扩散退火温度对10MnVNb/12Cr界面的影响。结果表明:复合管界面10MnVNb一侧组织为珠光体、马氏体和细小碳化物,12Cr一侧由铁素体、马氏体和少量碳化物组成。随扩散退火温度的升高,界面附近晶粒逐渐粗化,超过1200℃后出现明显过热;Cr元素在界面处发生明显扩散;马氏体峰强增加,碳化物类型由Cr3C2向Cr7C3过渡;退火和碳化物类型转变的综合作用下,界面两侧金属显微硬度出现先下降后上升的趋势。
