Effects of Argon Partial Pressure on Interfacial Shape of Porous Copper under Unidirectional Solidification

Abstract:

Based on the general mathematical model given in Ref.[6] for porous copper fabrication under unidirectional solidification, interfacial shapes including both of solid-liquid and gas-liquid interfaces are given. Effects of argon partial pressure on interfacial shapes are considered. Results show that interfacial shape changes from convex to concave with argon partial pressure increasing for fixed hydrogen pressure. However, increase of argon pressure does not result in changes of interfacial shapes and location changes of interfacial tip are not obvious as argon pressure increasing for fixed total pressure.
