| dc.description.abstract | Se presenta una metodología para el análisis de fallas en materiales metálicos que han fallado por fractura. El método propuesto se aplicó al estudio de una fractura presente en la mandíbula que soporta las probetas en una máquina universal para ensayos mecánicos de materiales. El análisis se estructuró en dos etapas: inicialmente, una inspección visual del elemento fallado, seguida de una serie de ensayos destructivos para identificar las características del material y la ocurrencia de la falla. La inspección visual identificó la morfología del material en la zona de falla, con brillo y una forma característica de fractura por clivaje, correspondiente a un material frágil y quebradizo. Mediante espectrometría de arco y chispa se identificó la composición del material. La metalografía mostró la formación de martensita típica de aceros de medio carbono sometidos a endurecimiento térmico, y la microscopía electrónica de barrido identificó la precipitación de carburos en el límite de grano, así como la presencia de huecos y otras inclusiones metálicas y no metálicas en la microestructura. La metodología propuesta permitió caracterizar la falla y proponer una solución adecuada mediante la identificación de posibles fallas ocultas que resuelvan la raíz del problema. | en_US |

| dc.description.abstractenglish | A methodology is presented to perform fault analysis in metal materials that have failed due to fracture. The proposed method was applied to the study of a fracture presented in the jaw supporting the test pieces in a universal machine used for mechanical tests on materials. The analysis was structured in two stages, initially a visual inspection of the failed element, followed by a series of destructive tests to identify the characteristics of the material and the occurrence of the failure. Visual inspection identified the morphology of the material in the fault zone with gloss and with a characteristic cleavage fracture shape corresponding to a fragile and brittle material. With arc and spark spectrometry the composition of the material was identified, Metallography showed the formation of martensite typical of medium-carbon steels subjected to thermal hardening and scanning electron microscopy identified the precipitation of carbides at the grain boundary, as well as the presence of gaps and other metallic and non-metallic inclusions in the microstructure. The proposed methodology allowed to characterize the fault and propose an appropriate solution by identifying possible hidden faults solving the root of the problem. | en_US |
