1. The effect of the carbon content on the grain size coarsening and on the magnetic properties of the semi processed electrical steels after the final annealing. / O efeito do carbono no aumento do tamanho de grão e nas propriedades magnéticas de aços elétricos semiprocessados após o recozimento final.
Annealing applied by the motors plants that are made on the semi processed electrical steels without an exact and precisious control of the decarburization on the lamination can brings undesirable results on the grain size coarsening and as a result an increasing on the core losses with a significant depreciation on the efficiency of the electrical motors.
