Ruido magnético de barkhausen: ensayo no destructivo para la evaluación de grados de dureza en aceros
Abstract
En el presente trabajo es presentada la aplicación de la técnica de medición del Ruido Magnético de Barkhausen (RMB) en la caracterización del perfil de dureza producido en un ensayo Jominy. Los efectos de las alteraciones en el material (AISI 4140 y AISI 5160), producidos por este ensayo han sido observados en las mediciones de RMB, encontrándose una buena correlación entre el valor inverso del parámetro RMBrms y las medidas de dureza Vickers realizadas. Los resultados presentados evidencian la viabilidad de la utilización de la técnica de medición del RMB como ensayo no destructivo en la identificación de diferentes niveles de dureza de materiales ferromagnéticosDownloads
