| সংক্ষিপ্ত: | Title screen In this work, model material formed by spark plasma sintering of dissimilar steels' particles was studied. The initial steels had dissimilar chemical composition - chromium-nickel steel (Fe-0.12C-18Cr-10Ni-1Ti) and high-carbon steel (Fe-0.8C). Microstructure and phase structure areas formed in the interaction of dissimilar microvolumes were examined. The results indicate that fine colonies of lamellar type with major phases of ferrite and cementite are formed in the zone of interaction between chemically heterogeneous particles. Austenite was found to be present in ferrite interlayers as small inclusions placed along their axis. A sequence of three phases in the direction perpendicular to the plates of cementite might look like: C-F-A-F-C etc. The austenite observed in ferrite interlayer of pearlite represents γ-phase which did not undergo polymorphic transformation in the process of the material cooling. The stabilization model of the austenite islands in ferrite interlayers of pearlite formed in the transition areas of dissimilar microvolumes' interaction is presented. |
