Embodiment Construction
[0051] Using the in-situ analysis method for inclusions in metal materials according to the present invention, the inclusions in three steel samples were analyzed. The three samples were: aluminum deoxidized steel LY26#, low carbon steel TG1#, pure steel BK1 #, the chemical compositions of the three samples are shown in Table 1.
[0052] First, according to the excitation state and excitation performance of the three samples, select a sample as a control sample for routine analysis. First, carry out metallographic detection and analysis. This method completely follows the requirements of metallographic sample preparation, and wire-cuts the sample. A block sample of 20mm×20mm×20mm was obtained, and after rough grinding, fine grinding, polishing and other processes, it was observed under a metallographic microscope. The metallographic microscope used was Neophot-21. Because the field of view observed under the microscope is limited, in order to make the observed field of view ba...
