Dealloying by peritectic melting
Mingwang Zhong, Alain Karma
Peritectic melting of Ti--Ag has been shown experimentally to form bicontinuous structures, but the mechanism remains unclear. Here we use phase-field simulations to show that thes…

Microstructure evolution during rapid solidification of hypoeutectic Al-Ag alloys near absolute stability
Brian Rodgers, Mingwang Zhong, Trevor Lyons +4
Microsegregation-free microstructures can form by solidifying at velocities beyond the absolute stability limit (), where solute partitioning is suppressed by a sta…

Phase-field model of alloy solidification far from chemical equilibrium at the solid-liquid interface
Kaihua Ji, Mingwang Zhong, Alain Karma
We further develop a recently introduced phase-field model of rapid alloy solidification [Ji et al., PRL 2023]. This model utilizes enhanced solute diffusivity within the spatially…
