Efecto del calor de entrada en las propiedades mecánicas y metalúrgicas de soldaduras de aceros avanzados de alta resistencia de plasticidad inducida por transformación TRIP unidos...
Published 2013“…El conocimiento del efecto térmico en la ZAC de las soldaduras es importante para la optimización de los parámetros de soldadura utilizados cuando se unen aceros avanzados de alta resistencia del tipo de Plasticidad Inducida por Deformación (TRIP por sus siglas en ingles), debido a que esto tendrá una gran influencia en las propiedades mecánicas y metalúrgicas finales de la unión soldada. Se evaluaron las propiedades mecánicas y metalúrgicas de tres muestras soldadas con entradas de calor alto 0.304 kJ/mm, medio 0.273 kJ/mm y bajo 0.248 kJ/mm, variando los parámetros de soldadura para obtener diferentes afectaciones térmicas e investigar las variaciones en las partes de la unión soldada como son, la soldadura, zona afectada por el calor y el metal base, debido al calor aplicado por el proceso de soldadura. …”
