High-strength carbon steels with hereditary fine crystal structure I. The effect of vibrogrinding on the parameters of the fine structure of iron powder particles

Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

We investigated the dependence of the specific Surface and of the parameters of the fine structure of powdered pure iron on the duration of vibrogrinding and their change in the process of reduction. It was shown that this is accompanied during the first 15–30 h as a result of deformation polygonization by the formation of a block structure. When ground powders are reduced, processes of polygonization occur intensively; however, regardless of that, the defectiveness of the crystal structure of the metal remains high, and this apparently is bound to have a substantial influence on the processes of dissolving carbon and structurization during the sintering of pellets.
