Abstract
1. Procedimiento de preparación de aleaciones ferrosas mediante el empleo de lantano, que permite reducir o suprimir ciertos defectos de dichas aleaciones ferrosas tales como las porosidades y cavidades de las fundiciones de grafito esferoidal, carburos de la fundición gris lamelar, mejorar la colabilidad, la aptitud al laminado y la isotropía de los aceros, y mejorar las propiedades mecánicas de dichas aleaciones ferrosas, caracterizado porque comprende la incorporación de por lo menos 0,0001% a aproximadamente 0,5 a 2% en peso de lantano a dicha aleación ferrosa en el curso de su elaboración.
