Austenitic grain size prediction in hot forging of a 20MnCr5 steel by numerical simulation using the JMAK model for industrial applications
Ivaniski, Thiago Marques; Epp, Jérémy; Zoch, Hans-Werner; Rocha, Alexandre da Silva (2019) [Journal article]Yield strength and toughness in steels are directly associated with hot forging processes, especially by controlling austenitic grain size and cooling conditions. The phenomenological JMAK model in macroscale has been ... -
Constitutive modelling of high temperature flow behaviour for a low carbon high silicon bainitic steel
Ivaniski, Thiago Marques; Souza, Tomaz Fantin de; Epp, Jérémy; Rocha, Alexandre da Silva (2020) [Journal article]It is well recognized the importance of the rheological characterization for the development of the steel in thermomechanical treatments, especially for the mechanical properties improvement of bainitic steels in subsequent ... -
