| description | Metal composites produced through the liquid metal dealloying (LMD) process feature an advanced matrix-matrix composite structure, where two metallic materials form a continuous, three-dimensional interconnected network. This study investigates the effects of TiCu precursor compositions on dealloying behavior and microstructural evolution in liquid Mg, using Ti50Cu50 and Ti30Cu70 precursors. The initial microstructure of the precursor significantly influences dealloying kinetics and phase transitions. The single-phase Ti50Cu50 precursor exhibits a faster initial dealloying rate due to its homogeneous structure, yet complete dealloying requires 90 min. In contrast, the dual-phase Ti30Cu70 precursor achieves complete dealloying in 30 min, demonstrating the impact of a higher Cu concentration on accelerating the process kinetics. Additionally, the study explores the coarsening behavior and hardness variations during the LMD process, along with the microstructural characteristics of Mg-Ti composites fabricated from these two precursors. The findings highlight the critical role of precursor composition in tailoring the microstructure and properties of Mg-Ti composites produced through the LMD process, demonstrating its potential for advanced composite material manufacturing. |
