Influência da microestrutura inicial para a cinética de reação de esferoidização em um aço SAE1080

Abstract

The SAE 1080 steels aresteels having a very high hardness, therefore it is of utmost importance to achieve this decrease hardness to forming work such as machining, to achieve reduction in hardness of the material was taken to spheroidizing treatment,which is a heat treatment which achieves lower hardness levels, and is characterized by a microstructure consisting of spherical particles uniformly dispersed carbide in a ferritic matrix which is known to spheroidite, this effect of reduction in hardness occurs mainly because of the small area boundaries per unit volume and hence the plastic deformation is not so restricted that gives a soft material, this structure was analyzed to obtain the best possible situationwith greater operational ease.
