Abstract 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
