Hardness distribution over cross-section of grooved rails

[摘要] Head hardened rails have been introduced In order to extend the rail-replacement cycles for Zagreb tram tracks. During their precurving, the rail cracking occurred. Hardness tests were performed and tensile strength was calculated to establish whether unu
