Microstructure characteristics of the model spring steel 51CrV4 = Značilnosti mikrostrukture modelnega vzmetnega jekla 51CrV4Torkar, Matjaž ...There are many data on solidification processes in the literature, but there are no relevant comparisons performed for the formation of an as-cast microstructure, the formation of gas porosity, and ... the influence of different cooling rates on the solidification of the molten, non-killed spring steel 51CrV4. 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.Source: Materiali in tehnologije = Materials and technology. - ISSN 1580-2949 (Letn. 48, št. 4, jul.-avg. 2014, str. 537-543)Type of material - article, component part ; adult, seriousPublish date - 2014Language - englishCOBISS.SI-ID - 1067690
