Abstract In order to study the thermal processing range of composite steel rebars coated with 2205 stainless steel,Gleeble 3800 was used for thermal simulation experiments,and the high-temperature rheological curve and thermal processing diagram of 2205 stainless steel were obtained,and the start rolling temperature of composite steel rebars was determined to be no less than 1 150 ℃. The numerical simulation of the rough rolling and finish rolling passes of the composite rebar was carried out using the finite element software. The results show that:during the rough rolling deformation,the strain is concentrated on the surface layer and 1/4 position of the rolling part. With the deformation continuous to penetrate into the core,the stainless steel cladding layer is thinner where the plastic strain is larger. In the process of finishing the rolling pass of k1,it is found that the thickness of the stainless steel cladding is the thinnest at the root of the transverse rib and the thickest at the crest of the transverse rib. After the study on the interface of the composite steel bar,it is found that the diffusion distance of Cr,Ni,and Mo is 18-20 μm. The microstructure from carbon steel to stainless steel is ferrite and pearlite microstructure,decarburization microstructure,composite interface,austenitic stainless steel microstructure,ferrite,and austenitic stainless steel microstructure.
