用透射电镜、扫描电镜、能谱分析仪研究了３１６Ｌ／１６ＭｎＲ热轧双金属复合板界面组织，相结构和成分变化。热轧复合为扩散型冶金结合，元素扩散范围在５０μｍ范围内。近界面钢侧为铁素体、少量马氏体和珠光体组织；近界面不锈钢侧为变形拉长和再结晶的奥氏体，奥氏体晶界上连续析出Ｍ_（２３）Ｃ_６；界面上奥氏体、铁素体和马氏体共存。
The interfacial microstructures and composition alteration of hot-rolled 316L/ 16MnR composite plate have been observed by TEM,SEM and X-ray energy spcetrum techniques. The hot-rolled composite is a diffusion process, and the diffusion range of the elements is about 50 μm. The side of steel next to interface consists of ferrite, small amount of martensite and pearlite, while the side of the stainless steel consists of the elongated and recrystallized austenite graius. The continuously precipitated carbide M23C6 has been observed along the austenite boundaries. The microstructure at the interfaceshows the coexistence of ferrite, martensite and austenite
