Combined carbon content assessment method for powder metallurgy

Powder metallurgy (PM) lacks a clear method to analyse the combined carbon content based on metallography visualisation, and this article describes the creation of such a method for powder materials. Different methods are used to analyse combined carbon within metallurgical samples, and the hardness of components within the automotive industry is related to this question. The main aim of this paper is to determine if optical microscopy provides a reliable means to assess the combined carbon content. For checking these items, the Optical Microscope will be used, density, hardness of sinter material, and particle size laser analysis of powder for creating the observed compact, and SEM microscope. This investigation provides standardised rules that can be implemented within any material laboratory. The analysis of powder particle size, hardness test, density check, and the investigation of the structure of powder element are presented.
