Thermodynamic and diffusion kinetic studies of the Fe-Co system

Thermodynamic Descriptions of the Co–Zr and Co–Fe–Zr Systems

“…Their calculated results reproduced the experimental data better, hence the thermodynamic parameters of Saenko et al [14] are directly Fig. 1 Co-Fe phase diagram assessed by Wang et al [12] adopted in this work. Fig.…”

“…Guillermet, [15] Ohnuma et al [16] and Turchanin et al [17] carried out the thermodynamic studies of the Co-Fe system, but their calculated magnetic properties did not completely reproduce the experimental data. [18][19][20] Wang et al [12] conducted the first-principles calculations and heat capacity measurements and performed a detailed thermodynamic assessment of the Co-Fe system. Their thermodynamic parameters [12] are directly adopted in the current work.…”

“…Recently, the Co-Fe-Zr isothermal sections between 1273 and 1573 K have been experimentally studied by Wang et al [11] , and the Co-Fe, Co-Zr and Fe-Zr subsystems have been thermodynamically assessed by several researchers. [12][13][14] Whereas the Co-Zr thermodynamic parameters. [13] still need to be adjusted because of the inappropriate thermodynamic model of CoZr and lowtemperature decomposition of CoZr 3 .…”

Local discontinuous Galerkin methods with explicit Runge‐Kutta time marching for nonlinear carburizing model

“…Mathematically, the carburizing process can be described by a diffusion equation, for example, a simple 1dimensional diffusion model was studied in previous studies, [1][2][3] where the diffusion coefficients were assumed to be a constant. However, the diffusion coefficient varies with systems almost for any realistic problem, for example, previous works [4][5][6][7] and so on. In the experiment, the diffusion coefficients are observed to be concentration dependent.…”
