Vanadium in Cold-rolled Sheet Steels
In hot rolled products, which are the subject of other presentations here, vanadium has been used for many years in high strength products, often in combination with other microalloying additions such as niobium or titanium. Vanadium can provide important contributions via both precipitation strengthening and ferrite grain refinement (due to austenite conditioning during thermomechanical proces...
متن کاملInfluence of silicon on cementite precipitation in steels
The mechanism by which relatively small concentrations of silicon influence the precipitation of cementite from carbon supersaturated austenite and ferrite are investigated. It is found that one condition for the retardation of cementite is that the latter must grow under para-equilibrium conditions, i.e. the silicon must be trapped in the cementite. However, this is not a sufficient condition ...
متن کاملDilatometric analysis of cementite dissolution in hypereutectoid steels containing Cr
Cementite dissolution in hypereutectoid steels containing Cr is analyzed using dilatometry combined with the consideration of the carbon content in the austenite. The results suggest that the austenite transformed from the mixture of ferrite and cementite can be approximated to have a carbon content corresponding to equilibrium with ferrite. The overall dissolution behavior of cementite is desc...
متن کاملElectropulse - induced cementite nanoparticle formation in deformed pearlitic steels
Passing one electric-current pulse through deformed pearlitic steel wires at room temperature causes the formation of cementite particles around 30 nm in size. This is found not only in some particular locations but throughout the cementite area, which reveals a different mechanism from traditional spheroidization of cementite plates because the latter leads to the formation of particles with m...
متن کاملGlobal recrystallisation model of low carbon sheet steels with different cementite contents
This paper discusses the influence of Particle Stimulated Nucleation (PSN) on the overall process of nucleation and subsequent grain growth in low carbon (LC) steels and proposes a global recrystallisation kinetics model based on fundamental physical metallurgy principles. The model takes into account the cementite content, which is dependent on the nominal carbon content, and the second phase ...
