Microstructure Evolution of Cold-Rolled Carbide-Free Bainite Steel Sheets During Continuous Annealing Process

Metals
A modified carbide-free bainite (CFB) steel has been developed, building on existing alloys for compatibility with commercial continuous annealing lines (CALs), featuring a low austenitization temperature and short overaging time.

Deformation of inclusions in rail steel due to rolling contact [PDF]

, 2012
Rolling contact fatigue (RCF) is a significant problem in the rail industry as it causes rapid and difficult to detect cracks. Inclusions present in the material can have an adverse effect on the RCF life of rails.
