“…To solve the problem, spheroidizing heat treatment is performed on high carbon steels. This process breaks up the lamellar cementites into small globular fragments and thus enhances the continuity of ferrite matrix, which in turn, increases the ductility and decreases the hardness [1]. Reduction of hardness is not always desired for machining operation.…”

“…However, the carbide nodules in the spheroidal condition remained structurally unaffected beneath the surface [9]. Fegredo et al [10] examined the effects of spheroidization on the wear rates of pearlitic railway steels. The study on the average ferrite distance between the edges of carbides.…”

“…The study on the average ferrite distance between the edges of carbides. The authors noted that coarse pearlite and spheroidization increased this length, which allowed for dislocations to move more freely, resulting in higher wear rates [10]. Diao et al [11] compared the wear resistance of three railway steels with different 3 microstructures.…”

“…Todo ello, además de disminuir la soldabilidad de estos aceros, hace variar, notablemente, el comportamiento frente al desgaste, de esas dos zonas. Por otra parte, existen trabajos previos en los que se estudia el comportamiento al desgaste de estos aceros en las vías ferroviarias en los que se pone de manifiesto la influencia del las inclusiones de MnS en la velocidad al desgaste de estos materiales [10][11][12][13] . Sin embargo, en estos casos, el material no formaba una unión soldada y no se ha evaluado el comportamiento de estos materiales en uniones soldadas.…”
