Effect of the microsegregation on martensitic and bainitic reactions in a high carbon-high silicon cast steel
(Molecular Diversity Preservation International, 2020-05)
Casting processes show some weaknesses. A particular problem is presented when the workpiece needs to be subjected to heat treatments to achieve a desired microstructure. This problem arises from the microsegregation ...
Estudo da viabilidade de formação de nitreto de boro em aços inoxidáveis ferríticos
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2020-03-02)
Since the 90s, the petroleum industry has been conducting research on alloys that are wear and corrosion resistant once several equipment parts used in the oil exploitation, extraction and production, such as pipes, joints, ...

FeNbP in ultra-low carbon Nb-added steel containing high P
(Elsevier B.V., 2000-09-01)
Precipitation of FeTiP is reported to occur in Ti-added IF steels containing high P during thermomechanical processing. An ultra-low carbon (ULC) Nb-added steel ingot containing a higher P content (< 0.8 wt-%) was produced ...

Melhoria no padrão de escoamento do aço líquido no distribuidor do lingotamento contínuo 01 da APERAM Inox América do Sul
(Universidade Federal de Minas GeraisUFMG, 2014-06-04)
In addition to distributing and feeding liquid steel into the moulds, the continuous casting tundish has a significant effect on the floatation of non-metallic inclusions. Flow modifiers, such as dam, weir and turbulence ...
Two-phase thermo-mechanical and macrosegregation modelling of binary alloys solidification with emphasis on the secondary cooling stage of steel slab continuous casting processes
(John Wiley & Sons Ltd, 2006-12)
As an approach towards a better modelling of solidification problems, we introduce a thermomechanical and macrosegregation model that considers a solidifying alloy as a binary mixture made of a liquid and a solid phase. ...
Thermal stress evaluation in the steel continuous casting process
(Wiley, 2006-12)
Two numerical models for the thermal stress and plastic strain analysis in the solid shell at the initial stage of a steel continuous casting process, are presented and their performances evaluated. First, a numerical ...
