Embodiment

[0095] The method of the present invention and the M method in DIN50602 were used to grade 12 areas in a piece of free-cutting steel materials respectively. The comparison results are shown in Table 1. Here the relationship between the area and grade of manganese sulfide inclusions is A=2 n , Where A is the area of ​​manganese sulfide inclusions and n is the number of grades. During the evaluation process, if the area of ​​the manganese sulfide inclusions measured is between n and n+1, they are rounded down and rated as n.

Abstract

The invention belongs to the technical field of surface micro-area analysis in the field of material science, and particularly relates to an analysis rating method for manganese sulfide inclusions in steel based on a calibration curve by the aid of a laser-induced breakdown spectroscope. The method includes the steps: (a) acquiring the calibration curve; (b) scanning analysis samples; (c) measuring ablation spots; (d) analyzing results. The signal intensity of component elements of the manganese sulfide inclusions is acquired, the calibration curve is used for inversion to obtain the length or the area of the manganese sulfide inclusions, sample pretreatment is simple, analysis is rapid, and scanning area is wide in range.

Description

Technical field [0001] The invention belongs to the technical field of surface microanalysis in the field of material science, and particularly relates to a method for analyzing and rating manganese sulfide inclusions in steel based on a calibration curve using a laser induced breakdown spectrometer. Background technique [0002] Modern industry has higher and higher requirements for the processing performance of steel products, requiring steel to contain a certain amount of sulfur, and using the generated sulfide to improve cutting performance. At the same time, in order to ensure comprehensive mechanical properties, it is necessary to control the content and form of sulfide. There are many instruments and methods that can be used to analyze the content and distribution of manganese sulfide inclusions in materials. The widely used materials in material research and industrial production mainly include metallurgical microscope, scanning electron microscope / energy spectrometer (SEM...
