Simulation of the Phase Diagrams for High-Chromium White Cast Irons and Multi-Component White Cast Irons

Abstract

In this study, simulation or computation of the phase diagrams for specific alloys of the high-Cr white cast irons and the multi-component white cast irons was performed by employing Thermo Calc software package and appropriate thermodynamics modules. The phase diagrams constructed were verified by thermal analysis (DSC), optical microscopy and X-ray diffraction analysis. Both the obtained phase transition points via DSC and the microstructures observed by optical microscopy and XRD analysis match well with the phase diagrams.
