Analysis Phases and Crystallographic Orientation of the grain of High Chromium Cast Iron Using EBSD Technique

Abstract


Grain orientation, properties, microstructure borders, and types and sizes of phases have had a major impact on the traits
of modern engineering materials. Therefore, it is important to study, analyze, and (further) control the method
of crystallizing alloys. One of the methods used to assess the orientation of grain growth is the EBSD technique.
EBSD (Electron Backscatter Diffraction Analysis) enables us to perform quantitative analyses on the microstructure of materials
(on a scale of millimetres to nanometres) in a scanning electron microscope. Using the EBSD technique can help us
gain valuable information about the following properties of crystalline materials: crystal orientation, disorientation, grain
boundaries, global and local texture, fractions recrystallization/deformation, stress analysis, characterization of intergranular boundaries, identification of phases, phase distribution, and so on. In this paper, we present the results of phase analysis
and crystallographic orientation of the grains of high chromium cast iron via EBSD. These were preliminary studies to determine
the possibility of using the EBSD technique for analyzing high chromium cast iron. Castings were produced under industrial
conditions, then samples were cut out and testing using the EBSD technique. This method proved to be effective for this type
of material.
