| 3 | EXPERIMENTAL-NUMERICAL AND MICROSTRUCTURAL CONTROL OF HOT STRIP ROLLING显示文摘On a local level, thermomechanical states during the passing of hot metallic material through the de- formation volume in a process of plane rolling with smooth rools were analysed by an experimental-nu- merical method. These states,which are markedly inhomogeneous in the length as well as in the height of the deformation zone,were taken as the basis for physical simulation of rolling the material at a certain lavel(i. e. stream line) of the deformation zone.Their influences on local yield stresses and on the development of the microstructure were checked.The efficiency of physical simulation of rolling with the Gleeble 1500 simulating equipment was examined.The states at which the transport of metallic material through the deformation zone between smooth rolls takes place were analysed by a visioplastic method,while physical simulation of rolling was made by thermomechanically controlled cylindrical compression tests.The tests were made with industrially manufactrued X5Grni8.9 austenitic stainless steel. | R.
