Fig. 3: Effect of melt composition on dealloying kinetics and compositional evolution.
From: Topological control of liquid-metal-dealloyed structures
Phase-field simulations of dealloying of Ta15Ti85 alloys quantifying the distinct effects of Ti and Ag addition to Cu melts on dealloying kinetics measured by dealloying depth versus time (a), Ti concentration profiles in the liquid at a dealloying depth of 400 nm (Negative depths extend in the melt region outside the dealloyed structure. The dealloying front is at left). b Ta leak versus time (c), and solid fraction of dealloyed structures as a function of melt composition (d). The x axis in (d) is the concentration of the additional element (Ti for the green line and Ag for the purple line and experiment) in the melt.
