摘要: A specialized dealloying technique called thermal was developed over 10 years ago for certain biomedical materials. This method is not widely used synthesizing nanoporous metals. However, it offers advantages conventional processes fabrication of structures, and highly suitable refractory metals that may be susceptible to oxidation during chemical/electrochemical liquid metal dealloying. In this study, structures were successfully fabricated from magnesium-based precursor alloys via sublimation magnesium at elevated temperature under vacuum conditions. Different diffusion rates affect the resulting density amount retained in each material.
