During a relatively rapid solidification the majority of the dissolved gases remain entrapped and due to a solid shell being formed they cannot escape from the steel. The result is the formation of gas porosity and a shrinkage cavity. Here we present the results of an investigation of the appearance and distribution of gas bubbles and a shrinkage cavity as well as the characterization of an as-cast microstructure in ingots of model spring steel, cast and cooled in different ways"},{"@xml:lang":"sl","#text":"V literaturi je mnogo podatkov o procesu strjevanja, vendar pa ni podatkov o primerjavi med nastankom strjevalne strukture in nastankom poroznosti med strjevanjem nepomirjenega vzmetnega jekla 51CrV4. Pri relativno hitrem strjevanju večina raztopljenih plinov ostane ujetih v jeklu in zaradi nastanka skorje ne morejo pobegniti iz njega. Rezultat tega je nastanek plinske poroznosti in lunkerja.
