Resumen

Este trabajo abordó la formación de la fase sigma de dos maneras independientes: mediante rayos X y ensayos de corrosión en muestras soldadas. En este estudio, se observó que las condiciones de soldadura de 0,4 a 2,5 kJ/mm (el rango recomendado para AISD es de 0,5 a 1,5) no fueron suficientes para observar la precipitación de la fase sigma en el acero SAF 2507.
