Cyclic deformation mechanisms and microcracks behavior in high-strength bainitic steel
(Elsevier Science Sa, 2017-01)
The purpose of this investigation is to analyze the mechanisms of cyclic deformation and the initiation and propagation of microcracks during low cycle fatigue in the bainitic steel 16CrMnV7-7. The slip systems and their ...
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 ...
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 ...
Fatigue behavior of bainitic and martensitic super clean Cr–Si high strength steels.
(Oxford, 2014-04)
This study compares the fatigue behavior of quenched/tempered and austempered super clean Cr–Si high strength steels (HSS). The microstructure of the quenched and tempered steel consisted of tempered martensite and that ...
