Description
  • Efekty podmínek tváření za tepla na těchto ocelích jsou mnohem méně studované než je jejich význam pro praxi. Je nutné zdůraznit, že bainitická transformace je klíčová reakcí na obohacení netransformovaného austenitu o uhlík. Tato studie byla uskutečněná za účelem získat porozumění efektu termomechanického válcování za tepla na finální mikrostrukturu a mechanické vlastnosti C - Mn - Si TRIP ocelí. Základní podmínkou vzniku indukované plasticity u TRIP ocelí je stabilizace značného množství zbytkového austenitu směrem k nižším teplotám a následně vyvolaná deformačně indukovaná transformace na martensit. Specielně připravené stupňové vzorky byly válcována na laboratorní trati Tandem. Významnější deformace, vyšší hotovní tvářecí teplota a vyšší teplota výdrže v bainitické oblasti má za následek pokles deformačního odporu. Úměrně poklesu síly roste tažnost TRIP oceli (cs)
  • Effects of hot-rolling conditions on these steels are much less studied than their importance for practice would suggest. It should be emphasised that bainite transformation is the key reaction to enrich non-transformed austenite with carbon. This study was carried out in order to gain understanding of the effect of thermomechanical hot rolling on final microstructure and mechanical properties of C-Mn-Si TRIP steel. Fundamental of the transformation induced plasticity effect - TRIP is the stabilisation of substantial amount of retained austenite down to the ambient temperature by thermomechanical processing and its subsequent transformation into strain induced martensite as a consequence of applied plastic deformation. The special prepared stepped specimens were rolled on laboratory tandem mill. The effects of finish rolling temperature, strain and isothermal bainite transformation temperature on mechanical properties of mentioned TRIP steel were evaluated (mechanical properties were examined with te
