2 – OBJECTIVE To present through the metalogrfico assay and of its micrographical analysis with the aid of the microscope the morphology and structure of the material in study, being determined the micron-constituent compose that it. that these micron-constituent vary the type of analyzed league in accordance with and in accordance with the thermal, mechanical treatments, processes of manufacture and other processes the one that the material has been submitted. The importance of this examination elapses of the fact of the mechanical properties of a metal not only to depend on its chemical composition as well as of its texture. With effect, exactly material one can become malleable, dctil, fragile, elastic, tenacious, etc., as the texture that to present and that can be given by means of mechanical works or adjusted thermal treatments to it. 3 – USED MATERIALS AND METHODS?
