“…During CEC, I-phase precipitation and growth occur, which will affect the recovery and recrystallization. I-phase particles act as strong obstacles to the dislocation and grain boundary motion [19,32,33]. Since I-phase particles can inhibit the grain boundary motion, it will inhibit the recrystallization grain growth, i.e., the I-phase particle precipitation can cause Ġ to fall.…”

“…Combined with high specific strength, specific stiffness and excellent casting performance, magnesium and its alloys serve as the lightest structural material, and have become the focus of materials research [1,2]. In particular, magnesium alloy with long-period stacking ordered (LPSO) phases exhibit relatively high strength and good ductility, making them promising candidates for practical applications [3,4,5,6].…”

The morphology evolution of long-period stacking ordered (LPSO) phases on corrosion behavior of Mg95.33Zn2Y2.67 alloy is investigated systematically during as-cast, pre-extrusion heat-treated, as-extruded and post-extrusion heat-treated conditions. The second phases in the as-cast alloy are only LPSO phases with a few Y particles. The pre-extrusion heat treatment changed LPSO phases from blocks into a rudimentary rod shape with lamellar structure, subsequently into fine fragments by extrusion, and then into a regular rod shape with lamellar structure followed by post-extrusion heat treatment. Immersion tests and electrochemical measurements in 3.5 wt % NaCl solution reveal that the post-extrusion heat-treated alloy has the best corrosion resistance with the lowest corrosion rate. This is attributed to the rod-shaped LPSO phases, which could hinder corrosion proceeding, and result in corrosion orientated along the direction of rods and forming relatively dense long-strip corrosion products. Our findings demonstrate that the improved corrosion resistance of magnesium alloys with LPSO phases can be tailored effectively by the proceeding technology and post-heat treatment.
