| Abstract: |
In this work, we investigated the structure of doeutectoid steel 14G2, which is mainly used for welded structures. Two methods were used to analyze the structure of this steel: optical microscopy (Metam RV-22 and Neophot - 21) and atomic force microscopy (PHYWE Compact AFM) using the semicontact mode. The investigation of the microstructure of steel was carried out for two samples obtained by different heat treatment. The first sample was quenched in water and subsequent low-temperature tempering and had a uniform troost-martensitic structure. The second sample was quenched from the intercritical interval with subsequent low-temperature tempering and had a stitch structure. The results of studying the microstructure of both samples of steel 14G2 are presented. The analysis of AFM images made it possible to establish the geometric parameters of the structural components, to estimate their shape, relief, roughness, and fractal dimension of surface. |
