Microstructural and mechanical characterization of 9Cr-1Mo-1W weld metal

Abstract

This paper presents microstructural and mechanical characterization of E911 welds metal. The types and transformations of the phases and microstructures of all-weld metal have been investigated through scanning electron microscopy, optical microscope, x-ray diffraction analysis. The elemental analysis and mechanical tests of the weld metal was determined by x-ray fluorescence, hardness measurements, and tensile tests respectively. This study will contribute the understanding of microstructural progression, microstructure characterization and mechanical properties of E911 steel after the post-weld heat treatment (PWHT).
