Influence of Microstructure on Mechanical Properties of Bainitic Steels in Railway Applications [PDF]
Metals, 2019 Wheel−rail contact creates high stresses in both rails and wheels, which can lead to different damage, such as plastic deformation, wear and rolling contact fatigue (RCF).

Advanced Ultrahigh Strength Bainitic Steels [PDF]
Materials and Manufacturing Processes, 2007 The addition of about 2 wt.% of silicon to steel enables the production of a distinctive microstructure consisting of a mixture of bainitic ferrite, carbon-enriched retained austenite, and some martensite. With careful design, impressive combinations of strength and toughness have been reported for high-silicon bainitic steels.

Flow Stress Behaviour and Static Recrystallization Characteristics of Hot Deformed Austenite in Microalloyed Medium-Carbon Bainitic Steels [PDF]
Metals, 2021 In the past decade, efforts have been focused on developing very fine, medium-carbon bainitic steels via the low-temperature (typically 300–400 °C) ausforming process, which not only enables shorter isothermal holding times for bainitic transformation at

Status and Progress of Super-Bainitic Steels [PDF]
Teshugang, 2012 The basic alloying elements in super-bainitic steels are C-Mn-Si and the structure of ultra-fine bainite, martensite and residual austenite is obtained by low temperature phase transformation at 300 〜500 ℃. In order to decrease critical cooling velocity,
