The main goal of the experiment was to assess the mechanical and microstructural properties of steel after additions of various amounts of micro-alloying elements. Heats with additions of V, Nb, Ti and Zr were prepared. Different austenitization temperatures and different deformations were applied. Their influence on the microstructure and mechanical properties was evaluatedČlanek obravnava termomehansko predelavo maloogljičnega mikrolegiranega jekla s fizikalno simulacijo na napravi za simulacijo realnega postopka kovanja. Glavni namen eksperimenta je bil ugotoviti mehanske lastnosti in mikrostrukturne značilnosti po dodatku različne količine mikrolegirnih elementov. Pripravljene so bile taline z dodatkom V, Nb, Ti in Zr. Uporabljene so bile različne temperature avstenitizacije in različne deformacije. Ocenjen je bil njihov vpliv na mikrostrukturo in mehanske lastnostiTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
