| Description
| - Trip steel multiphase microstructure is made up by polygonal ferrite matrix, bainite and significant fraction of retained austenite. Pearlite formation during thermomechanical processing disable sufficient retained austenite fraction stabilisation. Therefore pearlite formation is undesirable in TRIP steels. It is known that strain moves position of transformation curves to the left side toward to shorter times in CCT diagrams, however the transformation time reaction on hot deformation isn't fully explicit in TRIP steels. The influence of hot deformation on formation of pearlite was investigated by thermomechanical rolling in this paper. Experimental TRIP steels step samples were rolled. Four different strains were achieved on single sample during single pass due to step shape of sample. Microstructures of single steps of step samples were evaluated after rolling. Suppression of pearlite formation by means of strain magnitude was evaluated.

- Multifázová mikrostruktura TRIP oceli je tvořena polygonálním feritem, bainitem a významnou fází zbytkového austenitu. Tvorba perlitu v průběhu termomechanického zpracování znemožňuje stabilizaci dostatečného množství zbytkového austenitu. Proto je formování perlitu nežádoucí. Je známo, že deformace posouvá polohu jednotlivých transformačních křivek v CCT diagramech doleva, směrem ke kratším časům, avšak reakce transformačních křivek TRIP ocelí na deformaci za tepla není tak jednoznačná. V této práci byl sledován vliv deformace za tepla na tvorbu perlitu. Stupňovité vzorky z experimentálních TRIP ocelí byly termomechanicky válcovány. Díky stupňovitému tvaru vzorku bylo dosaženo čtyř velikostí deformace na jediném vzorku v průběhu jediného úběru. Po válcování byla hodnocena dosažená mikrostruktura jednotlivých stupňů vzorku. Tímto způsobem byla popsána míra potlačení perlitické transformace prostřednictvím deformace za tepla. (cs)
