“…On the other hand, there is a need for the early diagnosing of hydrogen damage in metallic constructions (19). The problem exists because obtained information about the susceptibility of alloys to hydrogen degradation consist of general characteristics that cannot be used for the prediction of the behaviour of a specific construction, since many parameters that control hydrogen absorption are unknown or have not been well-determined in terms of service life.…”

Design and development of advanced steel types require establishing an optimal combination of mechanical strength, resistance to hydrogen degradation and durability, among others; however, the available tools for assessing some of these properties are limited. A novel tool for supporting the design and development of steel types was therefore created. This tool, called TriDes, is based on the phenomenon of mechanically stimulated gas emission and allows for determining mechanical properties and hydrogen concentration locally, with high spatial resolution and during different phases of the service life of construction steel elements. Its applicability to the development of pipe steel with improved durability, as well as to steel types used in marine environments, has been investigated. RESUMEN: TriDes -una nueva herramienta para el diseño, desarrollo y evaluación no destructiva de aceros avanzados de construcción.El diseño y desarrollo de acero avanzado requiere establecer una combinación óptima de resistencia mecánica, resistencia a la degradación por hidrógeno y la durabilidad, entre otras. Sin embargo, las herramientas disponibles para evaluar experimentalmente algunas de estas propiedades son limitadas. Por lo tanto se creó una nueva herramienta, llamada TriDes. Esta técnica está basada en un principio físico distinto de los que se usan en las técnicas establecidas y combina la caracterización de hidrógeno en el acero en y la caracterización mecánica y/o tribológica. La técnica es portatil lo que permite determinar concentración local de hidrógeno con alta resolución espacial durante todo el ciclo de vida de elementos fabricados en acero y además evaluar la dureza y resistencia al desgaste del acero. Se ha investigado la capacidad de la técnica para el desarrollo de aceros para aplicaciones en gasoductos y construcciones marinas.
