Evolution of the texture of low-carbon microalloyed pipe steel in the seamless pipe manufacturing process

Abstract

A method of orientation microscopy (with the application of the EBSD technique) is used in investigation of the microstructure and texture in steel 0.08 % C-Cr-Mo-V formed at different stages of the seamless pipe manufacturing process, namely, after hot finishing and after full quenching with subsequent high-temperature tempering. It is shown that, at the final stage of hot finishing followed by heat treatment, the texture is represented by four scattered orientations. The found texture inheritance in the investigated material is presumably related to reproduction of special circa Σ3 boundaries between crystal grains at each phase transition. © 2016 Author(s).
