Gasar porous Mg-Ag alloys have been the focus of research due to their better biodegradable and catalytic performances. Pore structure inside the porous alloy mainly determines the practical aforementioned applications. To gain knowledge on the effect mechanism of alloying elements on pore structure, ordered porous MgAgx alloys were fabricated through Gasar method. The influence of Ag content on pore structures was analyzed. On one hand, a wider mushy zone with the Ag addition of 0.5 at.% promotes the forming of cellular crystals and then disturbs the continuous growth of pores. On the other hand, compared with the concentrated primary phase, the lamellar distribution of eutectic microstructure is beneficial to obtain regular pores. Based on the binary thermodynamic model, a ternary alloy system model describing the relationship between pore structures and experimental parameters was developed, and the predicted results were in good agreement with the experimental values. This research aimed to provide the theoretical guidance and technical basis for the subsequent detailed control of the porous structure of Gasar magnesium alloys. [ABSTRACT FROM AUTHOR] |
