Microstructural study of duplex stainless steel after turning using EBSD and X-ray diffraction analysis

Abstrakt

The aim of this research is a microstructural study of duplex stainless steel after turning. The electron backscatter diffraction and X-ray diffraction analyses were applied to analyse the surface and subsurface regions.

The gradients of Kernel Average Misorientation as a function of ank wear were investigated. It was found that the concentration of deformation depends on the subsurface depth, individual phases, and ank wear.

The similar behaviour but with a different inclination of grain size (determined by electron backscatter diffraction) and crystallite size (determined by X-ray diffraction) depending on ank wear was observed.
