Abstract
In order to achieve high mechanical characteristics of iron-based material, a modifier of highly-dispersed silicon carbide compound was used as master alloy that during electron beam melting provides a strengthened by nanoparticles structure of a material, suitable for further deformation processing. A nanosized powder was synthesized in the form of solid solution of carbon in silicon carbide, to create nanosized alloying modifiers for iron-based materials. A technology was developed for producing by electron beam melting iron-based ingots, alloyed by a highly-dispersed silicon carbide compound. Work was performed on producing 200 mm diameter iron ingots, with addition of 1, 2 and 3 % of synthesized nanosized alloying modifiers, based on silicon carbide. Thermal deformation processing of the ingots was conducted. The structure and properties of the produced material were studied. It was established that the produced materials based on iron with addition of nanosized silicon carbide are characterized by a dispersed size of the grains and nanosized carbide formations of platelike type. Increase of the concentration of nanosized silicon carbide from 1 to 3 % leads to formation of nanostructured pearlite structure. Ref. 11, Tabl. 3, Fig. 12.
