“…Previous studies 20,22 have shown that the microstructural characteristics of the second phase (especially grain size and volume fraction) can dramatically affect FCG behavior in steels with a soft matrix and a hard second phase. Therefore, the grain size and volume fraction of the second phase of the surface-and the middle-layer materials of the high-strength steel plates were quantified using Image-Pro Plus (IPP) software.…”

“…Tal fato era esperado visto que em um aquecimento fora do equilíbrio ocorre um superaquecimento dos constituintes originais (ferrita-perlita). Assim as suas decomposições ocorrem em maiores temperaturas do que aquelas previstas no equilíbrio [30].…”

“…A Figura 3 apresenta um comparativo entre as microestruturas temperadas a partir das diferentes Percebe-se que, com o aumento da temperatura de austenitização, houve um contínuo aumento da fração de martensita e, consequentemente, da dureza do material. Como argumentado na introdução deste trabalho, com o aumento da temperatura de austenitização intercrítica, a fração de austenita formada aumenta e, portanto, durante a têmpera, a mesma se transformará em martensita [30,31]. Pode-se observar que com o aumento da temperatura de austenitização de 750 °C para 880 °C, houve um incremento de 30% na fração de martensita o que justifica um aumento de aproximadamente 150HV na dureza deste aço.…”

“…[9] Multiphase steels with ferrite, martensite, and austenite have been much less studied than other consolidated types of stainless steels, such as ferritic, martensitic, austenitic, and duplex families. Faria et al [10] studied the influence of the microstructure on the mechanical properties of dualphase UNS S41003 stainless steel. Different amounts of ferrite and martensite were obtained by varying the austenitization time and temperature in the 815-1000°C range.…”
