Melt‐solid flow with diffusion‐controlled chemical reaction
Geophysical Research Letters, 1992 A simple model for melt‐solid two‐phase flow involving diffusion‐controlled chemical reaction is presented. The governing equations describing mass conservation were numerically integrated to clarify chemical evolution of the flow. The calculations show that the conditions for local equilibrium are violated concerning elements with small diffusion ...

Numerical exploration of diffusion-controlled solid-state reactions in cubic particles [PDF]
Materials Science and Engineering: B, 2003 Abstract The characteristics of diffusion-controlled solid-state reactions in cubic particles are explored in this study. In order to capture the three-dimensional reaction front, the diffusion equation, subject to an interfacial chemical reaction in cubic particles, is solved in a transient form using the finite volume method. How the unreacted core

Advanced Engineering Materials, EarlyView.Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...
