Resumo
In the present study, API 5L X70 pipeline steel samples were deformed by hot-rolling cooled in air or quenched in water and subsequently tempered at different temperatures. X-ray diffraction (XRD) and electron backscatter diffraction (EBSD) technique were used to analyze the texture evolution from the initiate state to rolling and tempering state at mid-thickness and near surface plane of all samples. The results showed that the mid-thickness region is richer in {100}//ND oriented grains known as more susceptible to crack formation and growth through. Hot deformed specimen showed dynamic recrystallization grains while quench tempered sample at 700°C evidenced recovery and grain growth.
