MICROSTRUCTURE AND DEFORMABILITY OF STEELS

Microstructural analysis of the deformability of steels and alloys has been insufficiently well investigated despite the fact that a specifi ed plasticity often cannot be achieved without providing the requisite stress state. The article presents data on a structural analysis of t he deformability of steels of different classes that has been conducte d by the Department of Heat Treatment and Metal Physics in cooperation with the Department of Pressure Treatment of Metals at the Urals Stat e Engineering University. The article is devoted to microstructural as pects of the deformability of structural steels. It is shown that the diagram of the stress state should be taken into account in analyzing the effect of structural factors. The dependence of the mechanism of s trengthening of ferrite-pearlite steels on the grain size and the effe ct of the content of pearlite on their strength properties are establi shed.
