ResumoO presente trabalho propôs-se avaliar a potencialidade de obtenção de uma microestrutura dual phase em um aço baixo carbono com microadição de molibdênio e nióbio, laminado a frio Full Hard. Os estudos foram suportados pelas análises da recristalização da ferrita, da fração volumétrica de austenita formada e sua evolução composicional/estrutural em função da temperatura de encharque no intervalo do campo intercrítico durante o encharque no tratamento térmico proposto com resfriamento em salmouraa fim de simular o encharque no recozimento contínuo. As caracterizações microestruturais e mecânicas foram avaliadas por Microscopia Ótica, Microscopia Eletrônica de Varredura (MEV), Dilatometria e ensaios de dureza Vickers, e confrontadas com estudos prévios via Espectroscopia de Raios-X de Dispersão de Energia (EDS). Palavras-chave: Bifásico; Aço baixo carbono com microadição de molibdênio e nióbio; Laminado a frio; Recozimento intercrítico. STRUCTURAL/COMPOSITIONAL EVOLUTION DURING INTERCRITICAL ANNEALING HEAT TREATMENT OF LOW CARBON STEEL WITH MO AND NB MICROADDITION AbstractThis present work aimed to evaluate the potential for obtaining a dual phase microstructure in a low carbon steel with molybdenum and niobium microaddition, cold rolled full hard. The study were explored by the ferrite recrystallization, the austenite formed volume fraction and compositional/ structural evolution as a function of soaking temperature on the intercritical range, during the soaking on the heat treatment proposedto simulate the soaking in continuous annealing. The microstructural and mechanical characterizations studied were evaluated by optical microscopy, scanning electron microscopy (SEM), dilatometry and Vickers hardness tests, and compared with previous spectroscopy by Energy Dispersive X-ray (EDS) studies.
