In this work, the microstructural characterization of one eutectoid steel through the Jominy test was carried out to define the transformation temperature and cooling rate that guarantees the formation of fine pearlite. Continuous cooling transformation (CCT) diagrams were built with the thermal response acquired during the Jominy test, optical microscopy and hardness tests, and compared with that calculated via JMatPro software. Also, the pearlite interlamellar spacing was measured and related to every cooling rate condition, in order to determine the relationship between microstructure and mechanical properties. The pearlite interlamellar spacing decreased while the cooling rate increased.
