Název v původním jazyce

The metallurgy evaluation of the relationship between the hot ductility shortness and the susceptibility to transverse cracking in CC products

Popis výsledku v původním jazyce

The work is devoted to the study of low-carbon steel microstructure on the plastic behaviour during the hot deformation at the critical temperature region. Under these conditions the steel microstructure consists of a ferrite and austenite mixture. The induced plastic deformation is concentrated in the intergranular ferrite zones having the allotriomorphic feature. The levels of applied strain rate and the heterogeneity effect of deformation in soft ferrite zones are analyzed. Simultaneously, the physical metallurgy characteriscics of the trough of ductility shortness found in dependence: R in A value - testing temperature are evaluated from point of view of the developing recrystallization process and of the possible limitation of this process, respectively. Further, the influences of the allotriomorphic ferrite morphology on the type of subsequent austenite decompositions products are investigated. The behaviour of allotriomorphic ferrite - austenite is very important on the subseque
