Modeling of textures and yield surfaces during recrystallization in IF steel sheets

Experimental and numerical study of the thermo-mechanical behavior of Al bi-crystal in tension using full field measurements and micromechanical modeling

“…The volumic plastic power is computed from the shear stress and the rate of shear strain on activated slip systems (Sarma et al, 1998;Hodowany et al, 2000;Choi et al, 2001) by:…”

Progress in mesoscopic modeling of microstructure evolution in steels

“…Some researchers simulated the microstructure and texture evolution during SRX in interstitial free (IF) steel using an MC method [96][97][98][99]. The simulation results of Hayakawa et al [98] showed that 111 || ND texture (-fiber), which is a typical rolling annealing texture in steel sheets, is obtained by a grain boundary nucleation mechanism.…”

“…The simulation results of Hayakawa et al [98] showed that 111 || ND texture (-fiber), which is a typical rolling annealing texture in steel sheets, is obtained by a grain boundary nucleation mechanism. Choi et al [96] calculated the yield surface of IF steels by coupling a viso-plastic self-consistent polycrystalline model with an MC technique. Montaño-Zuñiga et al [99] found that the -fiber orientation was dominant for the recrystallization due to its higher mobility.…”

Evaluation of stored energy in cold-rolled steels from EBSD data

“…Many researches have been conducted to optimize the macroscopic directionality of steel sheets [1][2][3]. In order to understand the evolution of microstructure in steels during cold rolling and recrystallization processes, many experimental and simulation works have been conducted in several length scales [4][5][6][7][8]. It is well known that the stored energy of subgrains in a deformed specimen is an important metallurgical factor in static recrystallization [9,10].…”

“…It is well known that the stored energy of subgrains in a deformed specimen is an important metallurgical factor in static recrystallization [9,10]. Many experimental and theoretical works have been carried out to evaluate the orientation-dependent stored energy of cold deformed polycrystalline materials [8,[11][12][13][14][15][16]. Rajmohan et al [11,12] derived the stored energy distribution function in the Euler angle space for cold-rolled steels by measuring the neutron diffraction line broadening.…”
