  • Microstructure characteristics of the model spring steel 51CrV4 = Značilnosti mikrostrukture modelnega vzmetnega jekla 51CrV4
    Torkar, 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.
