摘要: The article presents the characteristics of pearlite rail steels used in construction railways. discusses influence isothermal annealing process parameters on morphology and properties R260 steel. structure with a diverse was obtained physical modeling 3800 Gleeble Simulator. After heat treatment, existence microstructure colonies identified. They were smaller relation to after hot rolling process. It shown that reduction holding temperature influences decrease interlamellar distance On basis received results, dependences between resistance abrasive wear for operational conditions occurring switches estimated. tests conducted steel different Amsler stand rolling- sliding frictions. increases, when cementite decreases as load slip increase.
