  2. 1. Deformation Behaviour of Near Fully Pearlitic Railway Steels During Monotonic and Cyclic Loading

    Author : Niklas Köppen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCF; low cycle fatigue; Near fully pearlitic steels; work hardening; microstructure; tensile deformation; medium carbon steel;

    Abstract : The main conclusions that could be drawn from the present work are that the deformation behaviour of fully and near fully pearlitic steels is very similar and that a combination of low temperature, prestraining and high deformation rates is critical for the performance. This was shown from microscopy studies, tensile, impact and low cycle fatigue (LCF) testing. READ MORE

  4. 2. Comparability of Railway Rail Steels Low Cycle Fatigue Behaviour

    Author : Martin Schilke; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railway rail steel; strain energy density; Low cycle fatigue;

    Abstract : Several different kinds of steel are used for railway rails. From simple pearlitic steels for rarely used tracks over premium pearlitic steels for high performance lines to special bainitic, martensitic and austenitic steels for switches and crossings. Most of these steels have been trial and error developed over time in track. READ MORE
