Determination of the signal strength with the computer analysis of the material structure

At present, there are a number of software packages for the quantitative estimation of the characteristics of metallographic structure. One of the problems of using these software packages, however, is determining the phase to which the microstructure components belong. This paper proposes three methods based on the phase´s signal strength: 1) dotted, 2) graphical and 3) visual. In the dotted method, the intensity level is determined by using few points on the different particles of the same phase. In the graphical method, the phase´s intensity level is determined based on the graphical dependence of the phase quantity on the intensity level. In the visual method, the change in the intensity level results in the conversion of the phase color until all particles of the desired phase change color. Thus, the upper level for the dark phase and the lower for the light one can be determined.
