EFFECT OF STRUCTURE PARAMETERS ON THE FATIGUE LIFE OF RAIL STEEL

VLIYANIYE PARAMETROV STRUKTURY NA ZHIVUCHEST' REL'SOVOY STALI

An investigation to determine the effect of size of austenite grain and perlite dispersion (interlamellar distance) on the progagation of fatigue cracks and mechanical properties of rail steels is described. The chemical composition of the rail steels tested is given. Different dimensions of austenite grains were observed while changing the austenization temperature from 800 to 1250 degrees C. as well as dispersion of perlite as a function of cooling rates. The modes of heat treatment given to the various test specimens are described. The data obtained show the decisive effect of interphase-boundary density on rail-steel viability. The test equipment used for determining rail-steel viability, means for recording data, and the relation between perlite properties and the effect of interlamellar spacing are shown.
