Effect of microsegregation on carbide-free bainitic transformation in a high-silicon cast steel
(Maney Publishing, 2020-04)
A high silicon cast steel was studied in the as-cast condition in order to characterise its solidification macrostructure and microsegregation. The steel, poured into 32 mm-keel-block-shaped moulds, has a coarse solidification ...
Study of austempering kinetics of high silicon bainitic cast steels
(Maney Publishing, 2019-01)
This study investigates the effect of chemical composition and microsegregation on the bainitic transformation of high Si cast steels at two different austempering temperatures. The advance of the bainite precipitation as ...
Efeito da adição de Ni na microestrutura bainítica de um novo aço para roscas e cilindros de plastificação de polímeros
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2019-09-02)
Nitriding steels, such as DIN 1.8550, are used in the manufacture of screws and barrels for injection molding machines and plastic extruders. The hardening process of DIN 1.8550 occurs via water or oil quenching followed ...
Influence of the chemical composition on the ausferritic transformation in carbide-free bainitic cast steel
(Trans Tech Publication, 2014-05)
This work focuses on the study of the solid state transformations that take place during the austempering of high silicon carbide-free bainitic cast steels with different chemical composition. In order to get this objective ...

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 ...
Physical simulation as a tool to understand friction stir processed X80 pipeline steel plate complex microstructures
(2019-01-01)
The thermal cycles associated to friction stir welding and processing produce a wide range of microstructures, resulting in different mechanical behaviors along the weld. Most research efforts have focused on the development ...
