Ultrafine grained steels and the n coefficient of strain hardening
Though many efforts have been made to obtain ultrafine grained steels, the industrial production level has not yet been reached due to the plastic instability during forming. The present work shows, using three examples, that high strength low alloy steels produced by advanced thermom...

| description | Though many efforts have been made to obtain ultrafine grained steels, the industrial production level has not yet been reached due to the plastic instability during forming. The present work shows, using three examples, that high strength low alloy steels produced by advanced thermomechanical controlled rolling are in fact ultrafine grained steels with grain sizes below 5 m, establishing also a connection between the coefficient of strain hardening, mechanical strength and admissible thickness tolerances in steel sheets, in order to use these materials in cold work forming (bending and drawing). A minimum value of coefficient n must be reached in order to assure commercial use of the steel sheet. |

A través de tres ejemplos, el presente trabajo muestra que los aceros de alta resistencia y baja aleación manufacturados por la técnica de rolado avanzado termomecánicamente controlado, son de hecho aceros ultrafinos con tamaños de grano por debajo de 5 m, estableciendo además conexiones entre el coeficiente de endurecimiento por deformación, resistencia mecánica y tolerancia de los espesores admisibles en placas de acero, de forma que estos materiales puedan ser conformados en frío (plegado y estampado). El coeficiente n debe alcanzar un valor mínimo para asegurar el uso comercial de la placa de acero.Universidad de Montevideo2011-09-012024-07-12T12:56:16Z2024-07-12T12:56:16Zinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer reviewed articlesArtículos evaluados por paresArtigos revistos por parespublishedVersioninfo:eu-repo/semantics/publishedVersionhttp://revistas.um.edu.uy/index.php/ingenieria/article/view/289https://hdl.handle.net/20.500.12806/2465Memoria Investigaciones en Ingeniería; No. 9 (2011); 45-54Memoria Investigaciones en Ingeniería; Núm. 9 (2011); 45-54Memoria Investigaciones en Ingenieria; n. 9 (2011); 45-542301-11062301-1092reponame:REDUMinstname:Universidad de Montevideoinstacron:Universidad de MontevideoSpanish; CastilianDerechos de autor 2019 Roberto Gonz´ález, M.
