Risks

Bubbles From this image we can visualize as arrows indicated (Figure 10) the sprouting of bubbles in the material, formed during the process of manufacture of the iron carbon, where the rupture of the material occurs with more easiness. If the socket presented a graphite when sandpapered it would leave one black risk, in the studied steel did not have this graphite composition: the bubble only blew up. Figure 15? Bubbles? Incrustation Cementita Ferrite? Iron? Risks From this figure we can observe the ferrite presence brown color, cementita green color, incrustation/porosity black point, iron white color, risks in the horizontal line and diagonal line caused in the burnishing process, and bubbles formed in the manufacture of the steel carbon (it binds binary). 8 – CONCLUSION Therefore, from the presented data, the main conclusions of this work of which we carry through the assay is the study of metallurgic products, making possible to the determination of its constituent and its texture, generally carried through in previously polishing surfaces e, in general, attacked for an adequate reagent as in our assay. One notices that metallography is considered an analysis of great importance to also guarantee the quality of the materials in the process of manufacture and for the accomplishment of studies in the formation of new leagues of materials. This practical if becomes very complex and at the same time necessary, therefore the materials present different morphologies depending on the thermal treatments that had been applied it and also of the chemical composition employee, having to be analyzed before its application. Through the metalogrfica analysis of the steel it is possible to not only determine the classification of the steel, as well as, its physical, chemical composition and mechanics.
