Experimental microalloyed steel subjected to tempering heat treatments and its effect on hydrogen embrittlement
The influence of both, time and annealing temperature over the susceptibility to hydrogen embrittlement was evaluated in experimental microalloyed steel. Tempering heat treatments were carried out in a temperature range of 200-600 °C with several heat treatment times. They were hydrogen charged cath...

Experimental microalloyed steel subjected to tempering heat treatments and its effect on hydrogen embrittlementAcero microaleado experimental sometido a tratamientos térmicos de revenido y su efecto sobre la fragilización por hidrógenoVillalobos, JulioSerna, SergioCampillo, BernardoFlores, OsvaldoLópez Martínez, EdgarMicroalloyed steel, hydrogen embrittlement, Heat treatmentAcero microaleado, fragilización por hidrógeno, tratamientos térmicos.The influence of both, time and annealing temperature over the susceptibility to hydrogen embrittlement was evaluated in experimental microalloyed steel. Tempering heat treatments were carried out in a temperature range of 200-600 °C with several heat treatment times. They were hydrogen charged cathodically in a solution of H2SO4, using a current density of 40 mA/cm² during 1 and 12 hours of exposure. Susceptibility to hydrogen embrittlement and its effect on the mechanical properties in different treatment conditions were evaluated by tensile test. Also, were conducted hydrogen permeability tests to determine effective diffusion coefficients (Deff). The results showed that the mechanical properties decrease in ultimate tensile strength (UTS) and yield stress (YS) values as function of charging cathodic hydrogen times, without a clear trend over time and temperature heat treatment.La influencia del tiempo y temperatura de revenido en la susceptibilidad a la fragilización por hidrógeno, fue evaluada en un acero microaleado experimental. Los tratamientos térmicos de revenido se llevaron a cabo en un intervalo de temperaturas de 200 a 600 °C con diferentes tiempos. El proceso de cargado catódico de hidrógeno se realizó en una solución de H2SO4, utilizando una densidad de corriente de 40 mA/cm² durante una y 12 horas de exposición. La susceptibilidad a la fragilización por hidrógeno y su efecto sobre las propiedades mecánicas del acero fue evaluado en las distintas condiciones de tratamientos mediante ensayos de tensión. Además, se llevaron a cabo ensayos de permeabilidad de hidrógeno para determinar los coeficientes de difusión efectivos (Deff). Los resultados mostraron que las propiedades mecánicas disminuyen en sus valores de resistencia a la tracción (UTS) y límite elástico (YS) con un mayor tiempo de exposición de cargado catódico de hidrógeno, sin tener una tendencia definida con el tiempo y la temperatura de tratamiento térmico.Universidad Tecnológica de Panamá2016-09-082017-07-28T13:57:07Z2017-07-28T13:57:07Zinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttp://revistas.utp.ac.pa/index.php/id-tecnologico/article/view/590http://ridda2.utp.ac.pa/handle/123456789/18062219-67141680-8894I+D Tecnológico; Vol. 12, Núm. 1 (2016): Revista I+D Tecnológico; 14-21reponame:Repositorio Institucional de documento digitales de acceso abierto de la UTPinstname:Universidad Tecnológica de Panamáinstacron:U Tecnológica de Panamáspahttp://revistas.utp.ac.pa/index.php/id-tecnologico/article/view/590/pdfhttp://revistas.utp.ac.pa/index.php/id-tecnologico/article/view/590/htmlinfo:eu-repo/semantics/openAccesshttps://creativecommons.org/licenses/by-nc-sa/4.0/oai:ridda2.utp.ac.pa:123456789/18062019-12-06T14:50:25Z |
