The study focuses on the most extensively studied electrical steels and takes account of well-known and assumed influencing mechanisms involving chemical elements and aluminium nitride particles dissolved in solid solution during the formation of the steel's microstructure and texture. We concluded that the two main, influential mechanisms are as follows: first, inhibiting of the recovery and recrystallization processes; second, the energy changes associated with the grains of different orientation. It is assumed that the energy fields being created by the nitride particles are significant when it comes to slowing down growth and selecting the direction of the grain-boundarymobility. Two hypotheses were advanced relating to the asymmetry of the grain boundaries' properties and the availability of grains with different energies, which make it possible to explain the secondary-recrystallization processPreučili smo nekatere probleme določevanja teksture kovinskih materialov pri procesih poprave, primarne rekristalizacije, rasti zrn in sekundarne rekristalizacije. Raziskava je bila vodena na najbolj raziskanih orientiranih elektropločevinah. Študirali smo dobro poznana mehanizma vpliva kemijskih elementov in aluminijevih nitridov, raztopljenih v trdni raztopini, na oblikovanje strukture jekla in teksture. Ugotovljena sta bila dva glavna mehanizma vpliva, in sicer: prvi v zadržani popravi in rekristalizaciji in drugi v spremembi energije različno orientiranih zrn. Predpostavljamo, da nastanejo energijska polja zaradi nitridnih delcev, ki zavirajo rast zrn in vplivajo na mobilnost mej. Predloženi sta dve hipotezi asimetrija mej zrn in razpoložljivost zrn z različno energijo, s katero lahko razložimo proces sekundarne rekristalizacijeTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
