Influence of chemical composition and tempering treatment on toughness of bainitic 38MnV7 steel
Rancel, Lucia; Gómez, Manuel; Cabrera Marrero, José M.; Medina, Sebastián F. (2012)
Article
Accés obertThis work studies the influence of Mn and the V/N ratio on the toughness of 38MnV7 steel. Four steels with different Mn, N and Ti contents were studied. Lowering the Mn content to approximately 1.5% considerably enhanced ... -
Microstructural unit controlling cleavage crack propagation in high strength bainitic steels
Medina, Sebastián F.; Rancel, Lucia; Gómez, Manuel; Cabrera Marrero, José M.; Gutierrez, Isabel (2014-09)
Article
Accés obertThe strengthening mechanisms which are operative in bainite are very well known: small bainite packet, small width of the laths, dislocation density and size and number of carbide particles (Fe 3 C), among others. ... -
Theoretical and experimental nucleation and growth of precipitates in a medium carbon–vanadium steel
Medina, Sebastián F.; Ruiz-Bustinza, Íñigo; Robla, José; Calvo Muñoz, Jessica (Multidisciplinary Digital Publishing Institute (MDPI), 2017-02-07)
Article
Accés obertUsing the general theory of nucleation, the nucleation period, critical radius, and growth of particles were determined for a medium carbon V-steel. Several parameters were calculated, which have allowed the plotting of ...
