2. 1. Influence of thermal loading on mechanical properties of railway wheel steels

   Author : Krste Cvetkovski; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; contact creep.; rolling contact fatigue; martensite tempering; shear deformation; Railway wheel steels; heat treatment; residual stress; rapid heating; low cycle fatigue;

   Abstract : Material integrity and properties of wheels are critical in railway traffic, as wheels fulfil the important function of transferring load and traction from the vehicle to the rail track. Steels with a pearlitic microstructure are commonly used for wheels due to their height strength, low cost and good wear properties. READ MORE

4. 2. Temperature Stability of Railway Wheel Steels - Influence on Microstructure and Mechanical Properties

   Author : Krste Cvetkovski; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway; Diffusion; Low cycle fatigue; Fe‐Mn‐Si; Spheroidisation;

   Abstract : Being the single component transferring load and traction from the vehicle to the rail, the selection of materials and structural properties of railway wheels are critical. Carbon steel with a pearlitic microstructure is the most commonly used material due to its high strength, low cost and good wear properties. READ MORE
