Microstructure and Mechanical Properties of Laminated Mg-Based Composites

Abstract:

A new design method to achieve the laminated Ti-Al-Mg composites by stack processing with magnesium alloy plate, aluminum powder, titanium mesh and vacuum hot-pressed sintered. Sintering laminated material in different sintering temperature. The microstructure, ingredient, structure of laminated material and the interface of Ti-Al, Mg-Al were analyzed by SEM and EDS. Test results show that the optimum sintering temperature is 550 ^oC, and after sintered the aluminum powder and magnesium alloy plate hang together relatively tight by slight interface reaction, and aluminum powder can able to better coating the titanium mesh within the matrix. Mechanical property test found that titanium mesh is role-playing the reinforcement in laminated material, and makes the mechanical properties of laminated material improving significantly.
