dc.description.abstractHypereutectoid (1.15%C) steels with 0, 0.34, 0.9, 1.31, 1.47 and 1.68 wt. % aluminum were prepared. The samples were hot rolled at 1100°C followed by cooling in air. The microstructure of the as-rolled samples was characterized using field emission-scanning electron microscopy (FE-SEM). The electron back scattered diffraction (EBSD) technique was used to identify the grain boundary phases. The grain boundary phase is cementite in steels with aluminum content up to 1.31%Al. Phase diagram calculations show that aluminum increases the eutectoid temperature. The interlamellar spacing and pearlite colony size decrease with increase in aluminum content. Dilatometry measurements show that the transformation to pearlite occurs at a lower temperature in aluminum alloyed steels. The refinement of pearlite microstructure is discussed in the context of dilatometry results.-
