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.

A difração de raios-X (XRD) e a técnica de difração de elétron retroespalhado (EBSD) foram usadas para analisar a evolução da textura do estado inicial para o estado de laminação e têmpera na espessura média e próximo ao plano da superfície de todas as amostras. Os resultados mostraram que a região de espessura média é mais rica em grãos orientados {100} // ND, conhecidos como mais suscetíveis à formação e crescimento de fissuras. Amostra deformada a quente mostrou grãos de recristalização dinâmica, enquanto a amostra temperada a 700 ° C evidenciou recuperação e crescimento de grão.ABM Week - https://abmproceedings.com.br/; Editora Blucher2021-04-20T12:59:56Z2021-04-20T12:59:56Z2015info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/conferenceObjectapplication/pdfMASOUMI, Mohammad; ABREU, Hamilton Ferreira Gomes de.
