Steel rails bainìtico exceeding in resistance to failure by fatigue and wear resistance

摘要

Invention patent: b "steel rails bainu00ectico exceeding in resistance to failure by fatigue and wear resistance." d .High strength steel rails bainu00edtico has improved resistance to fatigue and wear failure required of the head of the rails to rail services for heavy load.The tracks of high strength steels bainu00edticos possessing excellent resistance to fatigue failures and damage contains constituents of the specific bands and consisting of structures bainu00edticas pAt least in part,They are characterized by the fact that the total area occupied by the carbides whose axes are greatest 100 to 100 nm in a given cross section of these structures bainu00edticas is responsible for 10 to 50 PoA cent of it.
