Vapor phase dealloying kinetics of MnZn alloys

Zhen Lu et al.

Summary: The study systematically investigated the kinetics and rate-controlling factors of vapor phase dealloying, and proposed a model to quantitatively describe the dealloying process. It was found that the dealloying velocity exhibits a transition from linear to power law behavior at a critical depth, resulting from the interplay between the dealloying process and microstructure.
