Purpose: At present, materials research in the area of SPD (severe plastic deformation) processes is very intensive. Materials processed by these techniques show better mechanical properties and have finer grain when compared to the input feedstock. The refined microstructure may be ultrafine-grained or nanostructured, where the grain size becomes less than 100 nm. One of the materials used for such...
Mathematical modeling of structure and mechanical properties of steel tubes production Kvačkaj T.1); Zemko M.1) 1) Department of Metal Forming, Faculty of Metallurgy, TU of Košice, Slovakia The article deals with FEM analysis, with mathematical modeling of structure evolution and with prediction of mechanical properties during hot rolling of seamless steel tubes. There is a brief description of stretch-reducing...
