Ruido Barkhausen y emisión magneto acústica para la caracterización de materiales ferromagnéticos/ Barkhausen noise and magneto acoustic emission in ferromagnetic materials

Resumen en español Se aplicaron las técnicas del Ruido Barkhausen (RB) y la Emisión Magneto-Acústica (EMA) a un material ferromagnético con el objetivo de correlacionar las señales obtenidas con los cambios microestructurales. En la primera etapa del trabajo se desarrolló un Sistema Integral de Medición (SIM) para las señales de RB y EMA. Se construyeron diferentes dispositivos tales como un yugo magnético, una fuente de corriente de baja frecuencia, un amplificador y filtro de fre (mas) cuencias y varios sensores de RB, a efectos de aplicar un campo magnético controlado y medir las señales de RB y EMA. Las primeras mediciones se realizaron sobre muestras de acero AISI 1020 con bajo contenido en carbono, inicialmente idénticas, que se habían preparado previamente mediante diferentes tratamientos termomecánicos. Una de las muestras se reservó como patrón; las otras fueron sometidas respectivamente a decarburización superficial, crecimiento de grano y deformación plástica. Se estudió también el efecto de los cambios microestructurales debidos al daño por radiación sobre las señales de RB y EMA. Para ellos se prepararon otras dos muestras de menor tamaño que las anteriores, a fin de que pudieran ser insertadas en el dispositivo de irradiación. La muestra irradiada fue sometida a un flujo de baja dosis de neutrones rápidos (3.6 10(15) n/cm²) y la otra se conservó como patrón. Los resultados fueron relevantes en todos los casos. En particular, el valor cuadrático medio (RMS) de las señales RB y EMA, resultó ser un parámetro cuya variación siguió adecuadamente los cambios microestrucurales. Los cambios en las señales magnéticas y la aparición de picos en las mismas se deben a diferentes mecanismos de anclaje de las paredes de los dominios magnéticos. El presente artículo conduce a recomendar el SIM desarrollado, como una valiosa herramienta de Ensayos No Destructivos (END) para materiales ferromagnéticos, siempre que el sistema se calibren previamente con una muestra patrón. Resumen en inglés The techniques of Barkhausen Noise (BN) and Magneto Acoustic Emission (MAE) were applied to a ferromagnetic material with the objective of correlating the obtained signals with the micro structural changes. The first step was the development of an Integral Measurement System (IMS) for the BN and MAE signals. Different devices as magnetic yoke, current source, amplifiers, frequency filters and different magnetic sensors were constructed. The first measurements were develop (mas) ed on an AISI 1020 steel, with low carbon content, submitted to different thermo mechanical treatments. One of the test probe was used as standard, the others were subjected to surface decarburation, grain growth and plastic deformation. The effects of radiation damage were also studied with BN and MAE. Other two smaller test pieces were prepared. The irradiated specimen was subject to a low flow of fast neutrons (3.6 10(15) n/cm²) and the other, was used as standard. In all cases the result were relevant. In particular, the RMS value of the BN and MAE signals resulted as an appropriated parameter whose variation followed adequately the microstuctural changes. The changes and the peaks in the signals are owed to the anchors of the magnetic domain walls. The present paper lead to recommend this IMS as a valuable tool in No Destructive Testting (NDT) for ferromagnetic materials, all times the system be previously calibrated with a standard probe.
