Development of ultra-high strength carbide-free bainitic cast steels
(Maney Publishing, 2020-11)
High-silicon cast steels and proper heat treatment cycles were designed in order to obtain carbide-free bainitic microstructures. The design process allowed to obtain the desired microstructures after heat treatment cycles ...
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 ...
Mechanical properties of a carbide-free bainitic cast steel with dispersed free ferrite
(Maney Publishing, 2020-01)
A high silicon, medium carbon cast steel was designed and heat-treated in order to develop microstructures composed of carbide-free bainite and small amounts of free ferrite, with the aim of obtaining high strength cast ...
Influence of the austempering time on the mechanical properties of carbide-free bainitic cast steels
(Springer, 2020-09)
Three medium-carbon, high-silicon cast steels with different alloy contents were austempered at 330 °C for different holding times in order to obtain carbide-free bainitic microstructures. Aiming at evaluating the influence ...
Wear analysis of PM compacts with bainitic microstructures, under unlubricated sliding conditions
(Elsevier, 2015-06-02)
Ferrous and non-ferrous alloys can be processed by PM. Complex shapes and good surface finishes can be achieved, leading to promising applications, if mechanical properties are demonstrated to be high enough. At the same ...
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 ...
Assessment of the austemperability of high-silicon cast steels through Jominy hardenability tests
(Maney Publishing, 2018-11)
The austemperability of seven high silicon cast steels with different alloy contents was characteri sed. The maximum round bar diameter that can be fully austempered changed from about 10 mm for an unalloyed steel to more ...
Evaluación de la resistencia al desgaste y a la corrosión de aceros bainíticos aleados con boro
(2015)
En los últimos años los aceros bainíticos han sido objeto de investigación debido a su amplio margen de aplicación a nivel industrial, como en la automovilística y en la construcción de rieles para trenes, citando algunos ...
