Influence of Eutectic-Type Inclusions on the Red Brittleness of Steels

The behavior of heterophase of the eutectic type inclusions (ETI) under different conditions of plastic deformation of industrial steels is studied. It is established that metal near inclusions damages with the formation of cracks and deformational cavitites caused by their melting. The melting temp...

Summary:The behavior of heterophase of the eutectic type inclusions (ETI) under different conditions of plastic deformation of industrial steels is studied. It is established that metal near inclusions damages with the formation of cracks and deformational cavitites caused by their melting. The melting temperatures of different ETI, as well as the temperature intervals for the formation of microdamages of various types during their deformation, were established. The melting of eutectic inclusions at the initial stages of deformation causes a sharp growth of cracks and cavities in steels, which promotes their red brittleness.
