EFFECT OF STRUCTURE OF RAIL STEEL ON ITS MAGNETIC PROPERTIES

O VLIYANII STRUKTURY REL'SOVOY STALI NA EYO MAGNITNYE SVOYSTVA

Studies of the magnetic properties of rail steel of standard chemical composition and having a lamellar structure are described. Magnetic parameters such as coercive force and maximum, minimum, and initial magnetic permeability of the rail steel are shown in graphical illustrations. Correlations are made between the saturation and residual magnetism of the metal. The relations studied suggest that the coercive force and magnetic permeability are the most sensitive indications of metal structure. This is further shown by plotting the change in coercive force, magnetic permeability, and hardness in relation to tempering temperatures. Experimental studies were performed by using two batches of rails produced at the Kuznetsk Metallurgical Combine and the test results are briefly described. It was found that work-hardening of rail-head metal which occurs on exposure to operating loads causes changes in hardness and the magnetic characteristics, such as coercive force, increase while magnetic permeability decreases.
