A presente investigação contempla o estudo do tratamento térmico de normalização de peças de aço em bruto de forja, e a viabilidade da sua substituição por um arrefecimento a temperatura controlada aproveitando o calor residual resultante do processo de forjamento, com todas as vantagens económicas associadas. O estudo foi desenvolvido em três grupos de amostras, um sem tratamento, outro com o tratamento de normalização, e outro com amostras obtidas por arrefecimento a temperatura controlada. Os resultados obtidos pelos ensaios de dureza e pela observação da microestrutura obtida, revelaram a viabilidade em se fazer a substituição do tratamento térmico de normalização pelo arrefecimento a temperatura controlada. ABSTRACT: The present research includes the study of a annealing heat treatment in a steel forging product, and the feasibility of being replaced by a controlled temperature cooling process, using the residual heat resultant from the forging process, with all the economical benefits. The study was developed in three groups of samples, one of them untreated, the other was annealed, and the last one with samples obtained from the controlled temperature cooling process. The hardness tests results and the microstructure observations obtained revealed the feasibility of the replacement of the annealing treatment for the controlled temperature cooling process.
