This paper study the synthesis and mechanical characterisation of steel (0.6% C) having lower than 1-micron grain size. There was severe plastic deformation in high pressure planetary ball milling and consolidation for obtaining bulk samples at temperatures between 350°C and 500°C. Studying grain size evolution showed that samples without subsequent heat treatment retained their nanocrystalline structure. Grain growth was controlled in heat-treated samples due to many nucleation points and the presence of cementite precipitates. The results obtained regarding hardness and grain size satisfactory agreed with the Hall-Petch ratio. The influence of the synthesis and mechanical characterisation techniques used in this work were compared to results mentioned in several references.
Este trabajo describe la obtención y caracterización mecánica de una aleación de acero 0,6% C con estructura de tamaño de grano inferior a 1 µm. El proceso para la obtención de piezas masivas se inicia sometiendo el polvo a severa deformación plástica en un molino planetario de bolas y a continuación se realiza la consolidación a alta presión y temperaturas entre 350 y 500 °C. El estudio de la evolución del tamaño de grano muestra que los consolidados sin tratamiento térmico posterior conservan su estructura en el rango nanométrico. En muestras con tratamiento térmico se observa un crecimiento controlado debido a los numerosos puntos de nucleación y la presencia de precipitados de cementita. Los resultados de dureza y tamaño de grano obtenidos cumplen la relación de Hall -Petch. Finalmente se analiza la influencia de las técnicas de obtención y de caracterización mecánica empleadas en este trabajo frente a diferentes fuentes bibliográficas.
