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 traitsof modern engineering materials. Therefore, it is important to study, analyze, and (further) control the methodof 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 usgain valuable information about the following properties of crystalline materials: crystal orientation, disorientation, grainboundaries, 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 analysisand crystallographic orientation of the grains of high chromium cast iron via EBSD. These were preliminary studies to determinethe possibility of using the EBSD technique for analyzing high chromium cast iron. Castings were produced under industrialconditions, then samples were cut out and testing using the EBSD technique. This method proved to be effective for this typeof material.
