Texture study across thickness of API X70 steel after hot deformation and diffe...
Masoumi, Mohammad; Herculano, Luís Flávio Gaspar; Almeida, Arthur Araújo; Béreš, Miloslav; Abreu, Hamilton Ferreira Gomes deIn the present study, the texture heterogeneity across the thickness of API X70 steel subjected to hot deformation and different posttreatments was investigated. X-ray diffraction and electron backscattered diffraction were used to analyze crystallographic orientation and grain boundary distributions at the center and surface layers of specimens. The initial material was rolled at 1000C to 67% reduction; then o...
Influência da microestrutura inicial para a cinética de reação de esferoidizaçã...
Almeida, Arthur Araújo; Martins, Jackson Gurgel; Silva, Marcelo José Gomes da; Abreu, Hamilton Ferreira Gomes deThe 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 carb...
