Phase field modeling the growth of Ni3Al layer in the β/γ diffusion couple of Ni–Al binary system

Temperature effect on the microstructural development of Al–Ni layered binary couples produced by an unconventional method

“…Within the temperature range of 647-700°C, diffusion of nickel from the liquid-phase intermetallic layer adjacent to the aluminium substrate takes place, as deduced from the endothermic reaction moving into the exothermic direction, which results in formation of primary NiAl 3 intermetallic phase particles in the Al + NiAl 3 eutectic. In contrast to the long-term studied Ni-rich part of Al-Ni binary system described in [38][39][40], it must be noted that, to the best authors' knowledge, there is still no clear and definite explanation of the diffusion mechanism in the line stoichiometric compounds (NiAl 3 phase), where variation in a chemical composition is not permitted and, therefore, the experimental data for further analyses are very important.…”

Phase-field investigation on the growth orientation angle of aluminum carbide with a needle-like structure at the surface of graphite particles

“…In the present work, we use a model with inputs from thermodynamical databases to investigate the growth of the aluminum carbide at the graphite-aluminum interface [29]. In the past years, the PF method has proved to be a powerful modeling technique to simulate the growth of the intermetallic phase [30][31][32][33][34]. Wang et al studied the evolution of the Mg 2 Si from two aspects: diffusion and reaction, by using a PF model [35].…”

Numerical and Experimental Investigations on the Growth of the Intermetallic Mg2Si Phase in Mg Infiltrated Si‐Foams

“…[12][13][14][15] For example, Park et al investigated the evolution of the Cu 3 Sn and Cu 6 Sn 5 intermetallic phases under electro-migration conditions, using a multiphase-field model. [16] Villanueva et al studied the growth of the intermetallic phase by incorporating fluid flow, phase change, and solute diffusion in the phase-field model.…”
