Quantitative Methods Used to Describe the Structure of Iron

Abstract:

The electrode processes are often studied on iron for the needs of hydrogen technologies. This paper presents the use of the resources of the “MicroScan” program in manual methods to determine the stereological parameters of the Armco iron. For this purpose, the average number of particles per one unit of the N_A surface area and the average surface area of the grains in the 〈A flat structure were determined, using the planimetric, the Jeffries and the comparative methods. The linear method was used to determine the average number of segments per one length unit of the N_L structure and the average length of the circuits of grains in the 〈L flat structure. It was found out that the mean values of the determined parameters were in line with the PN-84/H-04507 standard and small differences existing in the obtained results were due to the jumping character of the pattern scale of the mentioned standard. The relative error of the N_A and A parameters indicates that the planimetric method allows to achieve the most accurate measurement of the size of the grain.
