Un nuevo modelo fenomenológico y diferencial para predecir la respuesta mecánica de materiales metálicos policristalinos sometidos a deformación en caliente

Abstract: This paper presents a new phenomenological and differential model (that use differential equations) to predict the flow stress of a metallic polycrystalline material under hot working. The model, called MCC, depends on six parameters and uses two internal variables to consider the strain hardening, dynamic recovery and dynamic recrystallization processes that occur under hot working. The experimental validation of the MCC model has been carried out by means of stress-strain curves from torsion tests at high te… Show more

“…[30] The reduction process used was developed in previous studies. [31][32] This consists of using a numerical algorithm that performs automatic conversion of torque, number of turns and speed of rotation, into true stress, deformation and true strain rate, respectively. We chose the von Mises method for the conversion.…”

“…El proceso de captación de datos se ha realizado registrando el par y el número de vueltas {,N} para cada temperatura y velocidad. Los datos se han convertido a tensión y velocidad verdadera mediante un método diferencial [32][33][34] . Los datos obtenidos en etapas previas han sido tratados de corrección adiabática mediante un método desarrollado con anterioridad [35] .…”
