| Abstract Scope |
Liquid metal dealloying (LMD) is a novel process for fabricating metal-metal composites with a 3D bicontinuous structure through the selective dissolution of a precursor alloy in molten metal. The addition of alloying elements in the molten metal can affect the LMD behavior and the resultant microstructure and properties. In this study, two 3D interconnected Mg/Ti composites were fabricated by immersing TixCu(100-x) alloy precursors in Mg molten metals containing Zn or Ca. The microstructure and hardness of the Zn- and Ca-added Mg/Ti composites were compared using scanning electron microscopy, electron backscatter diffraction, hardness tests, and other techniques. Results reveal that Zn addition does not significantly alter the area fraction and size of the Mg and Ti matrices. In contrast, Ca addition results in a refinement of the Ti matrix and an increase in the hardness of the Mg/Ti composite. The dealloying behaviors and mechanical properties in Zn- and Ca-containing Mg molten metals are systematically analyzed. |
