What is Rail Material Composition and Properties about?
The document discusses the metallurgy requirements for rails used in Indian railways. Rails must withstand high mechanical forces from train loads and thermal stresses. They must have high resistance to wear, fatigue, and brittle fracture. Common rail sections used in India are 52kg, 60kg, and 90kg rails. Heavier axle loads up to 32.5 tons are being introduced, requiring improved rail metallurgy. Rail material properties depend on cooling rates - slow cooling forms pearlite which gives high strength but emb
